This soup is a great summer dish but it's even better because it doesn't get cooked! If you have a Vitamix with the soup setting, you can throw everything in there and put it on the soup setting and not worry. If not, you can warm it slightly before you eat it however if you warm it too much, you'll lose the nutrients of the raw veg.
3 cups of water
3 whole, large, ripe tomatoes
1 large cucumber
1 red bell pepper
1/2 of a sweet onion (mayan or spanish preferably)
