1 slice eggplant, 1/2-inch thick
1 slice onion
1 slice tomato
salt, pepper and oregano to taste
1 slice Mozzarella cheese

Layer all ingredients, starting with eggplant and ending with Mozzarella. Place in foil. Make a ball of foil and close loosely on top, so it does not stick to cheese. Bake on barbecue, lid down for 10 minutes.
