Preheat oven to 400°. Coat a baking dish with cooking spray. Season the chicken with S&P on both sides. In a wok style pan, drizzle in the olive oil and turn on to medium low heat. Add the minced garlic and cook for 2 minutes. Add the sliced mushrooms and saute for 2 minutes. Now add the spinach to the pan and put in the water. Cover and wilt the spinach (about a minute). Remove from heat. Drain and press out excess water.

Place the split and seasoned chicken in the baking dish. Drizzle a little olive oil on the chicken; then put the mushroom/spinach mixture onto the chicken pieces. Save a little for on top at end. Generously cover the pieces with shredded parmesan cheese (how much you like). Bake for 16 minutes. Check after 12 minutes to make sure the chicken is not burning or getting dry. Add more cheese if desired for the remaining cooking time. Remove from oven and serve.

I served this with a baked potato and it is very good!
