This vibrant taco salad has become my go to summer meal when I want something fresh yet satisfying. The secret lies in the shiitake walnut "meat" that mimics traditional ground beef with surprisingly authentic texture and flavor. I stumbled upon this combination during a particularly hot July when turning on the stove felt unbearable, and now my family requests it weekly. The best part is how the mushrooms and walnuts soak up all those Mexican spices, creating a protein rich base that even dedicated carnivores love.
I learned this technique from my vegetarian neighbor who showed me how to properly cook shiitakes until they release their moisture and develop that meaty bite. Now I keep bags of frozen mushrooms and walnuts specifically for this salad because my kids have started requesting it for school lunches.
Ingredients
- 2 corn tortillas, sliced into strips: Fresh tortillas work best here, look for ones without preservatives for the cleanest flavor when toasted
- Extra virgin olive oil: Use a good quality oil since you'll taste it in the finished salad
- 1 medium head romaine lettuce, chopped: Choose heads with crisp outer leaves and bright green color
- 1 cup shredded red cabbage: Adds gorgeous color and satisfying crunch that holds up well to dressing
- 1/2 cup cooked black beans, drained and rinsed: Canned works perfectly, just rinse to remove excess sodium
- 2 red radishes, thinly sliced: These add a peppery bite that balances the rich walnut meat
- 1/2 cup sliced cherry tomatoes and/or pico de gallo: Use the ripest tomatoes you can find for maximum juice and flavor
- 1 avocado, sliced: Wait until serving to slice to prevent browning
- Jalapeño slices, optional: Remove seeds for less heat or use pickled for tangy flavor
- Cilantro Lime Dressing, creamy avocado variation: This brings everything together with bright, zesty notes
- Sea salt and lime wedges for serving
For the Shiitake Taco "Meat"
- 1 tablespoon extra virgin olive oil: Helps the mushrooms brown properly
- 8 ounces shiitake mushrooms, stemmed and diced: Remove stems completely as they're tough and fibrous
- 1 cup crushed walnuts: Pulse in food processor until they resemble coarse breadcrumbs
- 1 tablespoon tamari: This adds deep umami flavor; soy sauce works as substitute
- 1 teaspoon chili powder: Use a good quality blend or make your own
- 1/2 teaspoon balsamic vinegar: Just a touch adds complexity and slight sweetness
- Sea salt and freshly ground black pepper to taste
Step by Step Instructions
- Prepare the Tortilla Strips:
- Preheat your oven to 400°F and line a baking sheet with parchment paper. Slice the tortillas into thin strips about 1/4 inch wide. Toss them with just enough olive oil to lightly coat each strip, then sprinkle with sea salt. Spread them in a single layer on your prepared baking sheet, making sure they don't overlap. Bake for 10 to 14 minutes, checking at the 10 minute mark. They should be golden brown and completely crispy when done. Set aside to cool while you prepare the rest of the salad.
- Create the Shiitake Walnut Meat:
- Heat the olive oil in a medium skillet over medium heat until it shimmers slightly. Add the diced shiitake mushrooms in a single layer and resist the urge to stir immediately. Let them cook undisturbed for 2 to 3 minutes to develop a nice brown color on one side. Then stir and continue cooking for another 2 to 3 minutes until they're golden brown and have released most of their moisture. The mushrooms should look slightly caramelized and smell earthy. Add the crushed walnuts and stir gently to combine. Toast the mixture for 1 to 2 minutes until the walnuts smell fragrant and nutty. Sprinkle in the tamari and chili powder, stirring to coat everything evenly. Finally, add the balsamic vinegar and give everything one final stir. Remove from heat and season with salt and pepper to taste. The mixture should taste savory and slightly spiced, resembling seasoned ground meat.
- Assemble Your Salad:
- Place the chopped romaine lettuce in your serving bowls as the base. Arrange the shredded red cabbage, black beans, and the warm shiitake walnut meat over the lettuce. Add the sliced radishes and cherry tomatoes, distributing them evenly for the best visual appeal. Top with sliced avocado and jalapeño slices if using. Add generous dollops of the cilantro lime avocado dressing wherever you like. Finish with a light drizzle of olive oil and a sprinkle of sea salt. Arrange the crispy tortilla strips on top and serve immediately with lime wedges and extra dressing on the side.

The shiitake and walnut combination was a complete accident that happened when I was cleaning out my refrigerator one afternoon. I had leftover mushrooms from another recipe and some walnuts that needed using up. When I tasted the mixture after seasoning it, I was shocked at how much it resembled the taco meat my grandmother used to make. Now I always keep both ingredients on hand because this has become one of our most requested meals.
Storage and Make Ahead Tips
Store each component separately in airtight containers in the refrigerator for the best results. The lettuce and cabbage will stay crisp for up to 5 days, while the shiitake walnut meat keeps for 4 days and actually improves in flavor as the seasonings meld together. The tortilla strips maintain their crunch for 3 days when stored in a sealed container at room temperature.
For meal prep success, assemble everything except the avocado and dressing in your containers. Add these right before eating to prevent the avocado from browning and the lettuce from wilting. I like to pack the dressing in small mason jars and the avocado slices in a separate container with a squeeze of lime juice.
Ingredient Substitutions and Variations
Feel free to swap the shiitake mushrooms for cremini or button mushrooms if that's what you have available, though shiitakes provide the most authentic meaty texture. Pecans or almonds work beautifully in place of walnuts, just pulse them to a similar consistency.
For the dressing, try swapping the cilantro lime version for a simple lime vinaigrette, or use store bought salsa verde for a completely different flavor profile. Greek yogurt mixed with lime juice and cumin makes an excellent creamy alternative if you're not avoiding dairy.

Serving Suggestions and Cultural Context
This salad works wonderfully as a light dinner served with warm corn tortillas on the side, or transform it into a heartier burrito bowl by reducing the lettuce and adding a scoop of cilantro lime rice at the bottom. For entertaining, set up a taco salad bar with all the components separated so guests can customize their own bowls.
The concept of taco salads became popular in American kitchens during the 1970s as Tex Mex cuisine gained mainstream appeal. While traditional versions relied heavily on ground beef and cheese, this plant based interpretation captures all those beloved flavors while incorporating more vegetables and healthier fats from the avocado and walnuts.
