Preheat the oven to 400°F.
Slice the chicken breast into 4 pieces and pound them until they're 1/2 inch thick.
In a small bowl, mix salt, pepper, dried oregano, and paprika.
Arrange the chicken in an 11×7 baking dish, seasoning both sides with the mixture.
In a measuring cup, blend heavy cream, green chilies, garlic cloves, and cornstarch until smooth.
Pour the creamy mixture over the chicken. Bake uncovered for 25-30 minutes.
Remove from the oven, sprinkle with spinach and shredded cheese, and bake for an extra 10 minutes or until the cheese is bubbly.
Serve over pasta or rice, and garnish with chopped Italian parsley and crushed red pepper, if desired. Enjoy your delightful and cheesy chicken creation!
