1 lb. browned ground beef
1 c. uncooked elbow macaroni
1 (15 oz.) jar spaghetti sauce
1 c. water
1 c. shredded Mozzarella cheese

Mix together all ingredients except cheese. Microwave on high for 14 minutes, sprinkle cheese on top and let stand 5 minutes. Cheese will melt and casserole will be ready.

A prepackaged noodle mix and chicken, plus a frozen vegetable makes this a complete meal. Leftover poultry and vegetables could easily be substituted.
