To make the salsa, mix the black beans, black-eyed peas, corn, red onion, bell pepper, chiles, and tomatoes together in a bowl. Toss vegetables with the Italian dressing, cilantro, garlic, and garlic salt until evenly blended. Cover, and refrigerate 6 hours or overnight.
Preheat a grill for medium-high heat.
About 45 minutes before serving time, place the chicken breasts in a baking dish and drizzle with lime juice and tequila. Sprinkle evenly with paprika, salt, and pepper. Cover the dish, refrigerate, and allow to marinate 10 minutes.
Remove chicken breasts from the marinade, and discard remaining marinade.
Cook the chicken breasts on the preheated grill until the juices run clear and the meat is no longer pink, 10 to 12 minutes.
To serve, place a lettuce leaf on each plate. Top with a chicken breast, and spoon Texas Bean Salsa over each, dividing evenly among servings. If desired, garnish with additional cilantro leaves and lime wedges.
