The easiest gluten free appetizer ever! Made with tomatoes, fresh mozzarella, basil, and a homemade balsamic reduction, all stacked on top of a Breton Gluten-Free Cracker!
Heat Balsamic vinegar over medium heat in a heavy bottomed sauce pan, stirring occasionally. Continue to simmer for 15-25 minutes, or until reduction thickens enough to coat a spoon.
Meanwhile, begin to assemble cracker stacks. Start by topping each cracker with a slice of mozzarella, followed by a slice of tomato, a basil leaf, and salt and pepper.
