Preheat oven to 350° degrees. Cook crumbled chorizo sausage in non-stick skillet over medium-high heat. Drain and set aside.
In bowl combine refried beans, cream cheese, sour cream & cumin. Beat together using electric mixer until well blended.
Stir in crumbled chorizo.
Spoon mixture into baking dish (I used a glass pie pan). Sprinkle with shredded queso Quesadilla cheese.
Bake 25 minutes or until cheese has browned.
