Tomatillo Cilantro Dressing

AKA Cafe Rio Dressing. This stuff is so so so so good. We use it when we have cafe rio salads but also on fish tacos. YUM! Here is my version of the dressing:
Ingredients

1 pkg. ranch dressing
1 cup mayonnaise
1 big handful cilantro (about 1 cup or more)
3 tomatillos
1/3 cup milk
1 jalapeno pepper (or less depending on how spicy)
Juice from half a lime

Put all the ingredients in blender and blend. Scrape down sides and blend until smooth. Best if you let it chill in fridge to let flavors blend together.
