Nacho Bake

1 pkg. Velveeta Shells and Cheese Dinner
1 lb. ground beef
1 pkg. taco seasoning
3/4 c. water
3/4 c. sour cream
8 oz. shredded cheddar cheese, divided
3/4 c. salsa (I use a little more than what the recipe calls for)
1/2 c. coarsely crushed tortilla chips
Preheat oven to 400. Prepare mac and cheese according to directions. While mac and cheese is cooking, brown grown beef and drain. Add taco seasoning mix and water to the meat; simmer for 5 min. Stir sour cream into prepared mac and cheese. Spoon half of the mac and cheese into 8" square baking dish. Top with layer of meat mixture, then half of shredded cheese, then remaining mac and cheese. Cover with foil and bake for 15 minutes. Remove from oven and top with salsa, remaining cheese, and crushed tortillas. Bake uncovered for 5 minutes. Makes 6 servings.
