Cucumber Yogurt Dressing/Dip

I whipped some of this up today and used it with my grilled veggies instead of sour cream!

1 cup chinks of peeled and seeded cucumber
1/2 cup coarsely chopped scallions
1 tablespoon tarragon
2 tablespoons chopped basil leaves
2 tablespoons lime jiuice
2 tablespoons olive oil
1/2 teaspoon salt
1 1/2 cups plain nonfat yogurt

Put all the ingredients minus the yogurt into the blender. Blend until smooth.
Transfer the mixture to a bowl and stir in Yogurt.

Keeps up to 10 days
