Here's the recipe, people!
1 C. Mayo
1 pkg. Hidden Valley Ranch dressing
1 C. buttermilk
2 cloves garlic
1 cup cilantro
Place in blender. Puree. Eat. Stop. Unbuckle pants. Eat some more. (putting on top of salad helps, but is not necessary:)
ps I like to add half of an avocado. It helps to thicken and it adds a yummy flavor.
