Preheat oven to 400°F. Chop chicken breasts into small pieces. Season with cumin, garlic powder, red chili flakes, salt, and pepper. Lay chicken pieces flat in a 9x13 baking dish.
Combine tomato, onion, jalapeno, corn, cilantro, and lime juice in a mixing bowl. Pour over the chicken pieces. Top with mozzarella.
Bake for 25-30 minutes or until the chicken is cooked through and no longer pink.
Serve over rice or in tortilla.
