                Cut up the chicken if you want, then lay it out with some lime wedges, handfuls of cilantro, and slices of avocado.

                Get your grill hot—aim for medium-high. If you can keep your hand just above the grate for a second before it feels way too hot, you’re good to go.

                Dip a folded piece of paper towel in olive oil, grab it with tongs, and wipe the hot grill grate. This will keep your food from sticking.

                Take those chicken breasts out of the fridge, dry them off with paper towels, and brush both sides with extra olive oil.

                Put chicken breasts on the grill. Leave them for 3–5 minutes each side till the inside hits 74°C and all the juices are clear. Let them rest a minute off the heat.

                Add the chicken breasts into your bowl, making sure you cover them all over with marinade. Stick a cover on or some plastic wrap and chill for at least half an hour (up to 4 hours if you’ve got time).

                Stir together olive oil, lime zest and juice, chopped cilantro, sugar, salt, and black pepper in a big bowl. Whisk until it all looks blended.

                Put your chicken breasts between two pieces of parchment or plastic wrap. Whack them with a rolling pin or meat mallet until they're spread out to about 1.5 cm thick all over.
