Ah yes, the famous Cafe Rio dressing. Who doesn't love it?
I usually do half the recipe and even that is plenty. It keeps in the fridge for a while and is amazing on tacos!
1 pkg ranch dressing mix
½ C sour cream
½ C mayo
1 C milk
½ bunch cilantro
1 clove garlic
2 tomatillos peeled and washed
½ jalapeno peppers without seeds
Blend together in blender or food processor.
