I came across this recipe on the Kraft Foods website, and it's really yummy! I use Kroger brand pizza sauce (Pizza Zip), and I would also recommend slightly undercooking the macaroni when you first prepare it so that it's not too tender in the end. This is an especially convenient dinner if you keep cooked lean ground beef in 1 lb portions in your freezer, like we do. :)
1 cup pizza sauce, divided
1 pkg. (7-1/4 oz.) KRAFT Macaroni & Cheese Dinner, prepared as directed on package
1 lb. extra-lean ground beef, cooked, divided
1 egg, lightly beaten
1/2 tsp. dried basil leaves
1/4 tsp. garlic powder
1/2 cup shredded Mozzarella cheese
Heat oven to 400°F. Reserve 1/4 cup pizza sauce.
Combine prepared macaroni dinner, 2/3 of the meat, remaining pizza sauce, egg and seasonings.
Spoon mixture into 9-inch pie plate. Top with remaining meat, reserved pizza sauce and cheese. Bake 15 minutes. Let stand 5 minutes before serving.
