Creamy Tomatillo Dressing

This salad dressing is amazing and if you like the Cafe Rio salad dressing, you will like this. I've made it before with low-fat mayo and sour cream and it's still pretty good.

1 buttermilk ranch dressing packet (make as per recipe)
2 tomatillos
1/2 bunch of cilantro
1 clove garlic
Juice of 1 lime
1 jalapeno (use the deeds if you like it spicy)

Use a food processor or blender to blend all the ingredients well. Refrigerate.
