In a shallow baking pan, combine the olive oil, lime zest, lime juice, finely chopped cilantro, minced garlic, pinch of salt and pepper. Mix to combine ingredients and make your marinade.
Lay the four pieces of chicken in the pan and then turn once so marinade covers the opposite side.
Place in the refrigerator for 30min. You can also make this a day ahead, cover and refrigerate overnight.
When ready to cook, preheat oven to 375°. Please the chicken with its marinade into a shallow baking dish. Cook until chicken is golden brown and cooked through about 25-30 minutes.
The dressing can be made while the chicken is cooking. See below for Cilantro Dressing recipe.
Remove chicken from oven after cooking and browning is complete. Assemble your salad, you can serve your dressing on the side or lightly toss with the mixed greens before plating. Slice your chicken into strips. Divide your mixed greens, top with your chicken slices and garnish.
