1 pound ground beef
1/2 pound rigatoni (cooked)
1 large jar spaghetti sauce (I used Ragu Traditonal)
1 large jar of mushrooms (drained)
1 pound mozzarella cheese
1 package sliced pepperoni
Brown the ground hamburger and drain off fat. Cook the Rigatoni and drain.
Combine the meat, Rigatoni, spaghetti sauce, mushrooms and mix well (this is called the sauce).
Layer in large baking pan: ½ the sauce and ½ the cheese. Another layer of sauce, then cheese. Top with sliced pepperoni.
Bake @ 350 degrees for 40 minutes.
The kids loved it...I did not even get to take a picture when it came out of the oven because everyone was so hungry!
