Creamy tomatillo dressing

I stumbled upon this recipe. It supposedly tastes like the Cafe Rio dressing. I haven't tried it, but want to later, so that is why I am posting it here. If anyone tries it leave a comment so we know how it is! Also, I have no idea how much this makes. It seems like kind of a lot, but I'm sure it would be a great dip for chips if there is a ton.

1 pkg. Ranch dressing mix
3 tomatillos (remove papery skin), rough chop
1 cup mayo
1 cup buttermilk
1 cup (or more) cilantro, rough chop
3 cloves garlic
1/8 tsp cayenne pepper
2 tsp green Tabasco sauce
juice from 1 lime

Dump everything in a blender or food processor and blend until smooth. Refrigerate in air-tight container .

Creamy Cilantro Dressing

Ingredients:
1/2 cup fresh cilantro leaves
1/4 cup buttermilk
1/4 cup fat-free mayo
1/8 t. sugar
3 drops hot pepper sauce (I probably added 8-10 drops!)

In a food processor or blender add all ingredients; cover and process until smooth. Serve over greens and veggies. Store in refrigerator.

Makes 1/2 cup

What I'll do differently next time: Add a little fresh lime juice.
