This is my favorite "go to" snack that I make in my toaster oven, but easily made in a regular oven.
1 Garlic Clove
Small tomatoes, sliced
Fresh Basil, chopped
Toast the bread. When it is hot and toasty, rub the garlic on the bread for the "garlicky" flavor. Top the toasted bread with mozzarella and the tomatoes. Then put the bread under the broiler till the cheese is melted. Once done, top with the fresh basil and sprinkle with salt.
