Taco Stuffed Shells
Brown the ground beef in a large skillet; drain fat. Stir in the taco seasoning and water; cook over low heat until thickened, about 5 minutes. Stir the refried beans and 3/4 cup Cheddar cheese into the taco meat. Spoon meat mixture into prepared pasta shells.
Spoon 1/4 cup salsa over the bottom of a 9×13 inch baking dish. Arrange filled shells over salsa. Spoon remaining salsa over shells.
Bake in preheated oven for 40 minutes. Remove from oven; sprinkle with sliced green onion and 1/4 cup shredded Cheddar cheese. Serve with sour cream.
