Cheesy Taco Casserole

2 cups uncooked spiral macaroni
1 pound lean ground beef
1 package taco seasoning mix
1 (15 oz.) can tomato sauce

1/4 cup milk
2 1/2 cups shredded sharp cheddar cheese (I used mild cheddar)

1 cup shredded lettuce or more
1 tomato, diced (about 1 cup)

Cook macaroni as directed on package.  In large skillet, brown meat; pour off fat.  Add taco mix, tomato sauce and beans; simmer uncovered 5 minutes.  Stir milk and 2 cups cheese into hot macaroni. 

In greased 3-quart baking dish, layer half macaroni, half meat mixture, half can onions, remaining macaroni and remaining meat.

Bake uncovered at 375 degrees 20-25 minutes or until hot.  To serve, top with lettuce, tomato and remaining cheese, onions and sour cream if desired.  Makes 6-8 servings.
