rinse and chop the tomatoes and basil, add garlic, olive oil, balsamic vinegar, salt, pepper and parmesan cheese,toss together, set aside.
slice italian bread in half inch slices, brush both sides of bread with olive oil, place bread on baking sheets and sprinkle lightly with garlic powder, bake at 350* just till crisp but not hard about 4 or 5 minutes. remove from oven.
top each slice of bread with 1 or 2 tablespoons of tomatoe mixture and sprinkle with a little shredded cheese and enjoy
if I'm having a lot of people over I just toast the bread and put in a basket and leave the tomatoe mixture in a bowl and the shredded cheese on the side for everyone to help themselves.
