Serve icy cold. Feel free to add your own favorite vegetables or other additions. I've added roasted red peppers and shrimp to make a yummy version. You can also used canned diced tomatoes (either plain, or with onions or peppers or both) with some of the juice instead of the fresh tomatoes. I sometimes double the amount of vinegar and lemon juice to make it more zippy. Keeps for at least a week in the refrigerator.
