An easy and delicious chilled soup. Perfect for a starter on a summer evening, or as the main course of a light lunch.
Add all of the gazpacho ingredients to a blender and puree. (If necessary to keep the ingredients from overflowing, do the pureeing in batches.) Transfer the gazpacho to a glass (or other non-reactive material) bowl and refrigerate for at least 1-2 hours.
Roughly mash the feta. Then add the sour cream and yogurt and mix well. Refrigerate until serving the gazpacho.
Pour gazpacho into bowls. Taste and add extra salt, pepper, and/or hot sauce if necessary. Add a dollop of feta crema and then a large spoonful of the topping vegetables.
Although I've specified sherry vinegar, which I find to be the right combination of tart and sweet for this soup, you can substitute red wine vinegar.
The choice of which vegetables to use as toppings is entirely up to you. I like the bite of Daikon radish. Also, its crispness and white color are a nice contrast to the smooth pinkish/red soup.
