Heat a large skillet over medium high heat and add 2 tablespoons of butter and 2 tablespoons of olive oil.
Season chicken breasts with salt and taco seasoning. Place in the hot skillet and cook for about 4 minutes per side or until golden brown and cooked through to 165℉. Set aside. *If they start to get too dark before they are fully cooked, you can finish in a 400℉ oven.
While the chicken is cooking, make the dressing. In a small bowl, whisk salsa, sour cream, ranch and lime juice together until combined. Stir in finely minced cilantro. Set aside.
Transfer chicken to a plate and add corn and black beans to the skillet. Stir to coat with the flavors in the skillet. Once warmed through, remove from heat and transfer to a serving bowl.
On a platter, layer lettuce, cheese, tomatoes, corn, black beans, sliced olives, green onions and avocado. Drizzle or toss with dressing.
Serve with extra chips and lime wedges on the side.
Notes
This is a great way to repurpose leftover chicken.
