Wash and dry eggplant and cut into 1/2 inch thick slices. Spread slices apart on baking sheet and bake for 20 minutes.
Remove from the oven and add toppings. Spoon on the marinara sauce (organic, no sugar added), add shredded cheese and pepperoni. Add extra toppings as desired -- chicken, bacon, ham, vegetables, mushrooms, olives, etc.
Broil in the oven, on high, until desired crispiness. Careful not to burn.
