Make. Eat. Enjoy. This is sometimes called "leftover salad" because you can add pretty much anything to it. Sometimes I'll add hard-boiled eggs, chunks of mozzarella, tuna, pepperoni, salami or garbanzo beans, depending on if it is going to be a side or main dish. Measurements are up to you -- whatever looks good!
Tomatoes, cut into chunks (or use grape or cherry tomatoes cut in half)
Red onion, thinly sliced
Bell pepper, thinly sliced
Cucumber, seeded and quartered
Fresh parsley, chopped
Salad dressing, approximately 1/2 c. (go with vinegar/oil-based dressing -- I love Newman's Own Low Fat Balsamic Vinaigrette)
6 c. cubed Italian bread, toasted
Combine tomatoes, onion, and dressing, and allow to sit for 20 minutes. Add peppers, cucumber, and parsley and let stand for another 15 minutes. Just before serving, add bread cubes and toss to blend.
