To a medium bowl, add all the marinade ingredients (4 boneless skinless chicken breasts3 tablespoons olive oil, 1 teaspoon garlic powder, 1 teaspoon ground cumin, 1/2 teaspoon smoked paprika, Kosher salt and ground pepper). Add the 4 boneless skinless chicken breasts and toss well to completely coat. Cover the bowl and let the chicken marinate in the fridge for at least 30 minutes.
Heat a grill pan or an outside grill over medium-high heat. Add the chicken and cook for 5-6 minutes per side or until golden brown and cooked through. Once the chicken is done grilling, allow it to sit for 5 minutes, then chop it.
Meanwhile, in a small blender, add all the dressing ingredients. ( 1 large avocado, 1/2 cup Greek yogurt, 1/4 cup olive oil1 tablespoon wine vinegar, 1 lime (juiced), 1/2 bunch fresh cilantro, 2 teaspoons dried oregano, and Kosher salt and pepper). Blend until smooth and creamy.
To a large salad bowl, add all the prepared veggies (4 cups romaine lettuce-chopped, 1 1/2 cup cherry tomatoes (quartered), 14 ounces black beans, 8 ounces corn, 1 medium red onionsliced, and 1/2 bunch fresh cilantro), and top with the grilled chicken. Drizzle with the avocado dressing and garnish with chopped fresh cilantro.
Notes
Chicken: I prefer using chicken breast since they are leaner. But you can use boneless chicken thighs. If you don't like chicken, use shrimp.
Lettuce: Romaine lettuce was used to make this salad, any other lettuce will do.
Greek yogurt: this can be replaced with plain whole milk yogurt.
Avocado oil can be used in place of olive oil
Make sure the avocado you use is firm and not overripe.
Allow the chicken to sit for 5 minutes before cutting them.
Do not overcook the chicken, it will come out dry and rubbery
