In a bowl, combine lime juice, tequila, triple sec, cilantro, garlic and red pepper flakes. Add chicken and marinate chicken for 3 hours or overnight (depending on how much you like the tequila flavor).
Marinate peppers and onion in Vegetable Marinade for 30 minutes to 1 hour.
Preheat outdoor grill to medium heat. Remove chicken from marinade and grill, turning once, until juices run clear, about 5 to 6 minutes per side. Drain peppers and onions, grill in a grill basket until tender and browned on edges, about 8 to 10 minutes.
Slice the chicken breast into 1/2-inch strips. Serve with peppers and onions, cheese, salsa and sour cream.
Combine all ingredients in a bowl.
