Spinach and Chicken with Proscuitto and Provolone

Chicken breasts
Fresh, washed spinach (lots of it – it cooks down)
Salt
Pepper
Prociutto ham, sliced (you buy this vacuum packed in the deli)
Provolone cheese, sliced
Fresh tomatoes, sliced
Sage
Olive oil
Spray casserole dish with cooking spray. Layer with spinach and then chicken. Lightly salt and pepper chicken. Place a piece of ham on each chicken breast and then a piece of cheese on top of the ham. Then place a slice or two of tomato on each breast. Drizzle with olive oil (not too much), and sprinkle with sage, salt, and pepper. Cover with foil. Bake at 400 for one hour or until chicken is cooked through.
