Preheat the oven to 400°F (200°C).

Slice the French baguette into 1/2-inch thick slices and place them on a baking sheet.

In a small bowl, mix together the olive oil, minced garlic, salt, and pepper. Brush the mixture onto both sides of each baguette slice.

Bake the baguette slices in the preheated oven for about 5-7 minutes, or until they are lightly toasted.

In another bowl, combine the diced cherry tomatoes, chopped basil, balsamic vinegar, salt, and pepper. Mix well.

Remove the toasted baguette slices from the oven. Top each slice with a spoonful of the tomato mixture.

Sprinkle shredded mozzarella cheese and grated Parmesan cheese over the top of each bruschetta.

Return the baking sheet to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.

Remove from the oven and let cool slightly before serving. Enjoy your Cheesy Bruschetta Bites warm!
