2 large cucumbers, peeled, seeds removed and roughly chopped
1/2 white onion, peeled and roughly chopped
1 avocado, peeled, pitted and roughly chopped
1/4 cup full-fat Greek yogurt
1/3 cup olive oil
Juice from 1 fresh lemon plus the zest
1/2 cup cold water (or more if needed to thin the soup)
1 tablespoon white wine or sherry vinegar
Salt and pepper, to taste
Chopped fresh cucumber and basil, for garnish
Add cucumbers, onion, avocado, yogurt, oil, lemon and lemon zest, 1/2 cup cold water and vinegar to a blender or for processor. Purée until smooth. If you'd like the soup thinner, slowly add more water and blend until it it the consistency you'd prefer. Season with salt and pepper to taste.
Chill for at least one hour before garnishing with cucumber pieces and basil. Serve and enjoy!
