Preheat the oven to 400 degrees. Line a baking sheet with the baguette slices. Toast the bread for 4-5 minutes on each side. Once you remove the bread from the oven, rub the raw garlic clove on each slice of baguette.
Dice the tomatoes very small, cut the basil into small ribbons and finely dice the shallot. Mix the tomatoes, basil, and shallots with a drizzle of olive oil and balsamic vinegar to taste. Season with sea salt and freshly cracked black pepper. Scoop a spoonful onto each baguette slice and serve. Add fresh mozzarella if you'd like. Enjoy!
