This old favorite has a number of variations. We like this one.
2 cups refried beans
1 cup sour cream
¼ cup taco sauce
Mash beans well or run through blender. Mix in sour cream and taco
sauce. Serve with corn chips or vegetable sticks. No taco sauce? Try
chopped green chile. Or enchilada sauce. Or chile powder to taste. Or a
minced jalapeño.
