Tomato, Onion, and Mozzarella Salad

I made this quick and easy salad for a 4th of July party at my co-worker's house! It's a simple combination of tomatoes, vidalia onions, and mozzarella cheese. The sauce was made with red wine vinegar, brown sugar, Worcestershire sauce, black pepper, canned tomato sauce, and extra-virgin olive oil.

I doubled the amount of onions, tomatoes, and mozzarella and still had plenty of sauce. It was quite popular and not much was left over!
