Eggplant Mozzarella Stacks- This site does not provide a recipe so here is what I did! Grill eggplant, shitake mushroom and red pepper (or whatever else you may have on hand). Set aside. Saute fresh spinach in garlic. When done, start to create your eggplant stack. Eggplant, mushroom, red pepper,. spinach, slice of fresh mozzarella, pesto or fresh basil and top with eggplant. Serve hot or cold.
