Mix the marinade ingredients together, set aside. Cube the chicken into small 1 inch sizes pieces. Add the chicken pieces and the marinade to a large ziplock bag, seal it. Massage the bag well with hands to ensure the chicken is fully covered in marinade.
Let the chicken sit in the fridge for 20 -45 minutes to marinate. *up to 24 hours max* When you are ready to cook, preheat the oven to 375º. Slice the bell peppers and any other veggies you are roasting. Add them to half of the large baking sheet. Drizzle them lightly with oil (about 1/2 tsp) and a pinch of salt and pepper.
Add the marinated chicken to the other half of the baking dish. Be sure the chicken pieces are not overlapping and have room to fully cook.
Bake in the oven for about 14-16 minutes or until the chicken is fully cooked and reaches an internal temp of 165º. (There will be liquid in the pan as it cooks so be sure to keep an eye on it)
Once the chicken is cooked through, take it out of the oven. There will be liquid in the pan, this juice is delicious and should be be drizzled or spooned over the bowls for extra flavor.
Assemble bowls! If making with rice/grains or lettuce, place this on the bottom and build the bowls with toppings. Add a generous dollop of sour cream and cotija or any cheese of choice. Squeeze a lime wedge over it, add more cilantro garnish and enjoy!
