Spray a pie plate with nonstick spray. Slice potato about 1/4" thick. Lay sli ces on bottom of the pan, overlapping slightly to form a "crust." Spray with no nstick spray. Bake at 400F for 40 min until slightly browned and potatoes are cooked.
My note: check potatoes after about 10 min, especially if some were cut thinner . Combine tomatoes, mushrooms, onion and seasonings. When crust is ready, spr ead with mushroom mixture. Top with olives then cheese. Bake for 10 minutes.
