Cilantro-Pistachio Pesto

I originally created this pesto to go with a quinoa & summer veggie dish on my blog (link to recipe: http://www.poorgirleatswell.com/2010/06/recipe-summer-veggies-with-quinoa.html), but I've had several readers tell me they use it in many other dishes. This can be used as a sauce for pastas or grains like quinoa, over grilled fish or chicken, or even as a cool, refreshing dip for vegetables. Warning: may cause severe pesto addiction!
