1 can Chipotle Chiles in Adobo Sauce (7 oz.)
Puree the chiles with their sauce in a blender; transfer to a large bowl. Heat oil in a large heavy skillet; saute tomatillo halves, onion and garlic until tender.

Cover and chill until ready to use. Bring to room temperature before serving. Makes about 2 cups.
