Preheat the oven to 350°F/180°C.
Season the chicken with salt, then in a small bowl combine chili powder, paprika, oregano, and cumin, and season the chicken with it from both sides.
In a large skillet over medium high heat, heat olive oil. Add the chicken and brown it for 3-4 minutes per side to give it color.
Optional: deglaze the pan with a splash of water to add lots of flavor!
Sprinkle the chicken with corn, then cover with salsa. Use a spatula to move the chicken around to get some of the salsa under each breast.
Bake in the preheated oven for 25 minutes or until the internal temp of the chicken is 165°F/74°C.
Remove the chicken from the oven, sprinkle it with shredded cheese, and place it under the broiler for a few minutes until the cheese is melted and bubbling.
Remove from the oven, and top with your favorite toppings.
