First, prepare your homemade salsa if you're making it from scratch, then set it aside.
Carefully slice each chicken breast horizontally to create two thinner cutlets, totaling 6 pieces. For extra tenderness and even cooking, gently pound them flat with a meat mallet.
Season both sides of the chicken cutlets generously with taco seasoning.
Heat a large, oven-safe skillet over medium heat and add the olive oil.
Sear the seasoned chicken for about 2 minutes on each side until lightly browned.
Pour your prepared salsa directly into the skillet, ensuring the chicken pieces are well coated.
Reduce the heat to a gentle simmer, then partially cover the skillet with a lid.
While the chicken simmers, preheat your oven to 450°F (230°C).
Continue to simmer until the chicken is fully cooked through and reaches an internal temperature of at least 165°F (74°C). Use a meat thermometer to confirm.
Sprinkle the shredded cheese evenly over the cooked chicken in the skillet.
Transfer the skillet to the preheated oven and bake for 5-7 minutes, or until the cheese is beautifully melted and bubbly.
Serve this healthy and flavorful dish warm!
