In a large bowl, combine the roma tomatoes, sun-dried tomatoes, garlic, vinegar, basil, salt, and pepper. Allow the mixture to sit for at least 10 minutes but several hours is better!
Cut the baguette into ¾-inch slices. On a baking sheet, arrange the baguette slices in a single layer. Brush with olive oil. Broil for 1 to 2 minutes, until slightly brown.
Top with Double Tomato Bruschetta mixture and sprinkle mozzarella cheese on top before serving.
