Preheat your oven to 400°F.
Sprinkle both sides of your chicken breasts with salt, pepper, and taco seasoning. Heat a large oven-safe skillet over medium-high heat. Grease with cooking spray or a drizzle of your favorite cooking oil. Once hot, add chicken breasts to the pan and cook until well-browned. Flip the breasts and repeat.
Once both sides of the breasts are browned, remove pan from heat and pour salsa over the top of the chicken. Place pan in the oven and bake for 15 to 25 minutes (the size of your chicken breasts will have a dramatic effect on cooking time), until an instant-read thermometer inserted into the center of the chicken reads 150°F.
Sprinkle cheese over the top and cook for another 5 to 10 minutes, until the chicken reaches 165°F. Remove from the oven and allow chicken to rest for 5 minutes before serving. Spoon extra salsa from the pan over white rice and serve with steamed green beans or broccoli and enjoy!
