Preheat broiler to high.

If sautéing garlic, heat 1 tablespoon olive oil in a small sauté pan over medium-high. Add garlic and cook until golden, stirring often to prevent burning.

In a bowl, combine garlic, tomatoes, balsamic, basil, salt, and pepper. Set aside.

Slice baguette into ¼-inch rounds and arrange in a single layer on a sheet pan. Brush with olive oil and broil for 1 minute. Flip baguette slices, brush with oil, and broil another minute, or until crisp.

Taste tomato mixture and adjust seasoning if needed, then serve with toasts.
