This easy dip is a lower-fat version of traditional hummus.
Preheat oven to 425 degrees. Wrap garlic heads in aluminum foil. Cook in oven until very soft, about 30 minutes. Remove from oven, and allow to cool in foil.
When cool, cut each head in half horizontally, and squeeze cloves into the bowl of a food processor. Add remaining ingredients, and puree until smooth. Add up to 2 tablespoons water if mixture is too thick.
Hummus can be refrigerated in an airtight container, up to 3 days.
