I just love the combination of tomatoes, baby mozzarella, basil, and balsamic vinegar.... whether it be in a salad or on a pizza. I came up with this idea for a sandwich because I wanted something I could easily carry in my hands that wouldn't necessarily dirty up a plate. It's light, summery, and very refreshing. Enjoy!!
On one slice of the bread, layer your tomatoes, top with the mozzarella cheese, drizzle with the olive oil and balsamic vinegar then sprinkle with the basil. Top with remaining slice of bread and serve.
