Costa Vida Cilantro Ranch

1 package of Hidden Valley buttermilk ranch dressing. (Prepare according to directions. I substitute 1 cup milk + 2 tsp. vinegar for 1 cup buttermilk.)
2 tomatillos or 3 Tbsp. salsa verde
1/4 bunch of cilantro
2 cloves garlic
1/4 cup lime juice
1/8 tsp Tabasco

Peel tomatillos and cut into fourths. Clean and rinse cilantro and remove large stems. Pour prepared ranch dressing in blender. Add cilantro leaves, tomatillos, garlic, lime juice, and tabasco. Blend until cilantro is finely chopped. Refrigerate for at least 2 hours, or until dressing has thickened.
