In a bowl, mix sour cream and Taco seasoning together until evenly mixed

In a square casserole dish, spread refried beans evenly on the bottom of the dish

Next, spread the sour cream/taco seasoning mix evenly on top of the refried beans

On top of the sour cream spread an even layer of shredded lettuce
