Instructions
If using one large chicken breast, cut it in half lengthwise (parallel to the cutting board) to create two thinner chicken breasts.
Whisk the marinade ingredients together in a medium sized bowl. Place chicken in the bowl, nestling it into the bowl so the marinade covers as much of it as possible, and cover the bowl tightly with plastic wrap. Marinate for one to four hours, but up to eight hours. (You can do this in a large zip top bag, too.)
Combine all of the Tex-Mex sauce ingredients (sour cream, mayonnaise, salsa, seasonings, lime zest, and lime juice) in a small bowl and whisk until totally combined and creamy. Taste and season with a pinch of salt if needed, then cover and refrigerate until ready to use.
Remove the marinated chicken from the refrigerator and let rest at room temperature for about 15 minutes before grilling. Grill over medium heat until cooked through and the internal temperature registers 165 F.
Transfer the grilled chicken to a small rimmed baking sheet (leaving a little space in between them), and divide the sauce over each chicken breast. Top each chicken breast with 1/4 cup of shredded cheese, and place under a high broil for a couple of minutes until the cheese is melted and bubbly.
Sprinkle crushed tortilla chips or crispy tortilla strips over the top of the chicken. Garnish with chopped green onion, pico de gallo, chopped cherry tomatoes, cilantro, or your favorite toppings! (You can also serve the chicken on top of tortilla chips if you like!)
