Nacho Beef Bake
In a large skillet, cook beef over medium heat until it is no longer pink; drain. Add the beans, water and taco seasoning; mash slightly. Cook and stir for 4-5 minutes or until heated thoroughly; set aside.
Unroll the crescent dough and press into the bottom and up the sides of a 13 x 9 inch baking dish coated with cooking spray; seal the seams and perforations. Spoon the beef mixture over the dough. Spread sour cream over beef mixture; sprinkle with cheese and chips.
Bake uncovered at 375 degrees for 20 minutes or until cheese is melted. Top with lettuce and tomatoes and more sour cream if desired. Serve immediately.
