The mozzarella cheese is only optional, I like to sprinkle a small amount on the top after broiling, adjust the garlic amount to suit taste, use *only* Roma (plum) tomatoes for this or the mixture will be too watery.
Top each slice of bread with equal amounts of the tomato mixture (make certain to cover the bread slice completely with the mixture or the bread will burn).
05Place the slices onto a large baking sheet.
06broil for about 2 minutes or until bubbly and lightly browned.
07Sprinkle lightly with finely shredded mozzarealla cheese if desired.
