Place chicken breast in a freezer bag. Remove the air and seal, then lightly pound chicken breast until thin.
Lay out the chicken breast on plastic wrap and season with a sprinkle of sea salt and pepper.
Put two tablespoons of pre-cooked cheesy rice and broccoli mix inside the middle of the chicken breast.
Place the half slice of American cheese on top of the cheesy rice and broccoli mix.
Roll the chicken breast tightly and tuck the sides in and stick toothpicks in them to keep it tight.
Place gently into a lightly sprayed casserole baking dish.
Bake at pre-heated 350 °F (175 °C) oven for about 25 minutes, depending on the thickness of the breast.
Remove from the oven and spray tops of chicken lightly with olive oil spray, then replace the chicken and broil for approximately 10 minutes or until golden brown. Can be served whole, or sliced. It makes a beautiful presentation when sliced in 2 inch slices and served on a thin layer of buttered rice.
