I got this recipe from my son. He made it last year in Texas when we were doing a big Mexican dinner. I have used it on tacos and you can just use it as a dip. Really good.
* One ripe avocado, peeled and seeded (don't use an unripe avocado)
* 1/4 cup non-fat greek yogurt or sour cream
* 1/4 cup chopped fresh cilantro
* 2 tablespoons milk
* 1 large clove garlic, minced
* juice of one lime
* Small pinch of kosher salt
Optional: one Serrano pepper or as much as you would like for heat.
Blend everything in a Bullet, Ninja, etc.
