Creamy Buttermilk Tomatillo Dressing ( great over taco salads!)

Creamy Buttermilk Tomatillo Dressing

1 buttermilk ranch dressing packet (I used Hidden Valley)
1/2 cup buttermilk
1/2 cup sour cream
1 cup mayonnaise
2 small tomatillos (or 1 large), husk removed and diced
1/2 bunch cilantro, or less (I use from 10-15 leaves, because Jason likes cilantro but doesn't LOVE it)
1-3 cloves garlic (I used 2), cut in 4 sections and toasted under broiler until tan
Juice of 1 lime (use 1/2 to start... I used a little more than half of a lime)
1 medium or small jalapeno (remove seeds)

1. Pour all ingredients into a blender and blend.
2. Refrigerate for 1 hour before serving.
