Stuffed Mushrooms

Wash the mushrooms, cut off the tip of the stems, and remove the stems. Chop the mushroom stems into very small bits. Coat the outer poriton of the caps with olive oil. Finely chop onion, garlic, and tomato. Fry onion and garlic in olive oil (just a little bit), until soft. Add mushroom bits, tomato, salt and pepper to taste. Fry until mushroom bits start to soften. Place mixture in mushroom caps, and fry or grill until caps soften. Serve.
