This hearty salad combines thick cubes of whole grain bread with tomatoes, black olives, cucumbers, and fontina cheese.
In a large bowl, whisk together vinegar and olive oil; season with salt and pepper.
Add bread, tomato, cucumber, fontina cheese, and Kalamata olives.
Toss well to combine. Transfer to an airtight container, and refrigerate until ready to serve, up to overnight. Garnish with fresh basil leaves, if desired.
You can use mozzarella instead of fontina cheese.
