I used to live in Houston and then moved to Atlanta where they didn't have a Chuy's. I had to have the recipe for Chuy's Creamy Jalapeno dip, so I called them and they gave it to me! That was 16 years ago and I still make it today, and people still ask me for the recipe

Here it is

1 package Hidden Valley Ranch dip mix
1 cup mayo (Hellman's or Best Foods)
1 (7 oz.) can tomatillo sauce (salsa verde)
1/2 cup cilantro
1 jalapeno chopped (remove seeds if you don't want it too spicy)

Put it all in a blender and buzz it. Chill for at least an hour before serving.

I serve it with cucumbers and grape tomatoes, and of course tortilla chips are good too.
