Bruschetta is a classic Italian appetizer that is simple yet bursting with flavors. Start by slicing a baguette into thick slices. Toast the slices until golden brown. In a bowl, combine diced tomatoes, minced garlic, fresh basil leaves, olive oil, balsamic vinegar, salt, and pepper. Let the mixture sit for a few minutes to allow the flavors to meld together. Spoon the tomato mixture onto the toasted bread slices. You can also top it with a sprinkle of Parmesan cheese or a drizzle of balsamic glaze. Serve as an appetizer or a light snack.
