In a medium bowl or large ziplock bag add all marinade ingredients - oil, lime juice, garlic, salt and spices. Add chicken and marinate for 30 minutes to 1 hour. (If chicken is thick you can use a meat tenderizer to create even thickness 2 cm).
While Chicken is marinating you can prepare your rice in the rice cooker or on the stove. Prep beans and corn. I like to mix a little seasoning (1/2 teaspoon chili powder, possibly salt) and lime juice to the black beans.
Preheat Grill to high heat. Clean the grates. Reduce heat to low and place the chicken on the grill for 7-10 per side until cooked through and internal temperature reads 170 degrees.
While the chicken is grilling you can prepare the other toppings and in a small bowl combine all the ingredients for the pico de gallo.
Let your family create their own bowls starting with rice, beans, corn and finishing with pico de gallo, lettuce, sour cream, avocado, chicken and cheese.
