Rub the 4 boneless skinless chicken breasts with the 1 tablespoon taco seasoning, Kosher salt and pepper and 1 tablespoon olive oil.
Place in a baking dish and bake for 25-30 minutes.
Meanwhile, chop and prepare the fresh salsa. (1 1/4 cup freshly chopped tomatoes, 1/4 cup finely diced onion, 1 Mexican spicy pepper, 1/4 cup minced fresh cilantro, 1 lime, and Kosher salt and pepper)
Remove the chicken from the oven, top with the fresh salsa and 1 cup shredded Cheddar.
Return to the oven and continue baking for 8-10 minutes, until the internal temperature reaches 165F and the cheese is fully melted.
Garnish with fresh cilantro and avocado, if desired.
Notes
Quick note: If the chicken breast is too thick, feel free to slice them in half lengthwise.
You may use boneless and skinless chicken thighs instead.
Don't want to use chicken? Use Salmon or cod. You will need to cook it for a shorter amount of time.
Use fresh ingredients if possible. I would recommend using fresh tomatoes, fresh parsley, and fresh cilantro.
Any pepper will work, like serrano, jalapeno, or Anaheim. You can deseed them if you do not like them too hot.
