Salad dressing, dip, or suck it down with a straw; it doesn't get any better than this.
1 Buttermilk Ranch dressing packet
Make it according to the directions.
In a food processor, pour in the ranch mixture and add:
1/2 a bunch of cilantro
1 clove garlic
juice of 1 lime
1 jalapeno (remove seeds, unless you like to live dangerously)
Process until smooth. Can be used and stored the same as regular ranch dressing.
