Preheat oven to 450 degrees. Sprinkle both sides of the chicken with the seasonings and bake for 10 minutes, until fully cooked, flipping halfway
Meanwhile, melt margarine over medium heat. Add minced garlic and sauté until fragrant, about two minutes. Add spinach, a sprinkle of salt and sauté in the margarine until completely wilted
Move spinach to the side of the pan and add sliced pepper to the other side. Sauté each side for two minutes. Set vegetables aside
Once chicken is cooked, top with spinach, mozzarella then pepper. Bake for another 2-3 minutes, until cheese is melted. Drizzle with balsamic glaze and enjoy!
