The story behind the recipe: So you think this sounds too easy...try it! This recipe doubles or triples easily...but the original quantities make for a huge amount of servings...
1 medium red onion, sliced
2 cups fresh mushrooms, sliced
2 large tomatoes, coarsely chopped
1 - 2 cloves garlic, minced
1 - 2 tps oregano
1 cup sharp cheddar cheese, grated
1 cup mozzarella cheese, grated
Extra cheese for topping.
Combine all ingredients and place in a greased baking dish (9x13). Top with extra cheese. Bake, uncovered, at 350F for 30 minutes. Do not overbake. (trust me when I say do not change anything)
