Slide baguette into 3/8 inch slices. Use the broiling feature in your oven to toast the bread. Turn the broiler on high, places the baguettes on a cookie sheet, and broil until the bread begins to turn brown. Remove cookie sheet from oven, then flip over and brown the other side. Slice the basil into tiny little strips by rolling several leaves together.
Assemble by placing a piece of the toasted bread onto a plate, add a thin slide of Mozzarella, then a thin slide of tomato, top with basil. Drizzle with balsamic vinegar reduction.
