Preheat oven to 375F/190C.
Slice your baguette into 1/2 inch slices and place on a baking sheet in a single layer.
Mix olive oil, half the garlic, and 1/8 tsp pepper in a small bowl.
Brush olive oil mixture onto baguette rounds using a pastry brush.
Bake for 12-15 minutes or until golden brown.
Mash cannellini beans with a fork then set aside.
In a bowl, combine diced tomatoes, salt, 1/8 tsp pepper, balsamic vinegar, remaining garlic, fresh basil and parmesan cheese.
Spread a thin layer of mashed beans onto each baked baguette.
Top each bean layer with 2 Tbsp of tomato mixture.
