Creamy Tomatillo Ranch Dressing

This is a take off of the delicious Cafe Rio Chain Restaurant's Creamy Tomatillo dressing.  It is delicious!  I make it without tomatillos sometimes too when I don't have any.  It is wonderful on top of this taco salad or this taco salad, quesadillas, etc.

SIMPLE VERSION:
1 ranch dressing packet prepared using pkt. recipe*(see note)
Juice of 1 lime
½-1 bunch of cilantro
EXTRA YUMMY ADD-INS:
2-3 tomatillos (can use 1/3 c. green salsa as a substitute)
1 large clove garlic
freshly ground pepper
1 jalepeno (no seeds)--omit this if you don't like things spicy
-Using a blender, blend all the ingredients until smooth and creamy.  Serve with quesadillas, taco salad, etc.
-*NOTE:  I'm a bit picky when it comes to my ranch...this is best using 1 c. 1% milk and and 1 c. KRAFT mayonnaise (don't use low fat!)
