Slice tomatoes. Spread slices out onto a baking sheet. Drizzle with olive oil and balsamic vinegar. Add salt pepper if desired. Turn oven to broil. Broil for ten minutes checking to make sure the tomatoes don't stick.

Brush bread with olive oil. Place oiled side of bread down in a skillet. Top with two basil leaves. Place tomatoes on basil leaves. Top with mozzarella cheese. Brush another slice of bread with oil. Place bread oiled side up on top of cheese.

Cook in a skillet until bottom slice is brown and then flip and brown the other side. Cook until both sides are browned and cheese is melted. Enjoy!
