I frequent a restaurant that serves something like this. After tinkering, I think I found my version!!
Toss tomatoes, cucumber, onion, fontina cheese, olives, basil, oregano, parsley, salt, and black pepper with olive oil and balsamic vinegar in a large bowl. Allow mixture to rest for 10 minutes.
Place bread cubes in a large dish. Pour tomato mixture over bread and toss to coat. Bread salad should be served within 2 hours.
