2 c (2 whole cukes) seeded, peeled and diced
1 c pesto*
1 1/2 c plain yogurt
3/4 c sour cream
2 T white vinegar
1/4 t salt
black pepper to taste
1 clove garlic, crushed

Combine all ingredients in blender. Blend until smooth. Chill and serve cold.

Pesto:

2 c fresh basil leaves
2 cloves garlic
1/4 c freshly grated parmesan cheese
1/3 c pine nuts or walnuts
1/2 c olive oil
salt and pepper

Combine in blender. With machine running, slowly pour in olive oil. When it is mixed to a thick sauce consistency, scrape down sides, taste, and season with salt and pepper.

NOTE: A fresh store-bought pesto such as Contadina, may be used instead of making your own.
