This is a simple, refreshing soup with a fresh garden flavor. Place two halved or roughly chopped tomatoes in the blender first, then add one roughly chopped cucumber and sea salt to taste, and blend until smooth. You will find that no additional water is needed to blend, since the tomatoes contain so much liquid, but you may need to use a spoon or spatula to press the ingredients down into the blender as you blend. Garnish with cucumber and yeast flakes (optional) or other desired garnish. Fresh herbs would also make a nice addition.
