Preheat your oven to 400°F.
Slice the chicken breast into four pieces and gently pound them until they're about 1/2 inch thick.
In a small bowl, mix sea salt, black pepper, dried oregano, and paprika.
Arrange the chicken breast in an 11x7 baking dish and season both sides with the spice mixture.
In a measuring cup, blend heavy cream, green chilies, garlic cloves, and cornstarch until smooth.
Pour the creamy mixture over the chicken. Bake in the oven, uncovered, for 25-30 minutes.
Take it out, sprinkle spinach and shredded cheese over the chicken, and bake uncovered for an additional 10 minutes or until the cheese is bubbly.
Serve over pasta or rice. If you like, garnish with chopped Italian parsley and crushed red pepper. Enjoy!
