Tear about 10 oz. stale crusty bread (from a 6-inch loaf) into bite-size pieces.

In a large bowl, combine the bread with 1/2 C. green olives, pitted and cracked (about 8 whole olives); 8 oz. fresh mozzarella, tom into pieces; 4 oz. prosciutto, torn into pieces; 4 plum tomatoes, cut into rough chunks; 1 can (15 oz.) butter beans, rinsed and drained; and 1 tsp. fresh oregano leaves.

Drizzle the salad with 2 tsp. balsamic vinegar and 2 T. extra-virgin olive oil, season with salt and pepper, toss, and serve.
