In a bowl, combine the olive oil, lime juice, garlic, chili powder, paprika, cumin, and oregano; season to taste.
¼ cup olive oil or avocado oil, 2 tbsp. fresh lime juice, 2 garlic cloves, ½ tbsp. chili powder, 1 tsp. paprika, 1 tsp. cumin powder, Sea salt and freshly ground black pepper, ½ tsp. dried oregano
Place chicken and vegetables in separate bowls and pour half of the mixture over the bell peppers and onions and the other over the sliced chicken; toss both until well combined.

Place the baking sheet in the oven for 5 to 6 minutes to preheat it.
Remove the baking sheet from the oven (careful, it’s hot!) and place chicken on it. Put back in the oven and bake for 8 to 10 minutes.
Turn chicken over and top with the sliced vegetables, put back in the oven, and cook another 15 to 20 minutes, or until chicken is cooked through and vegetables are tender.
Serve topped with cilantro and lime wedges.
