What's not to love in this cheesy, beefy, pasta bake? Since everything is already cooked, all you have to do is pop it in the oven for 20 minutes and let the mixture heat up and the cheese melt. -Patty Hough of Sun City, Arizona


  • 8 ounces uncooked mostaccioli
  • 1-1/2 pounds ground beef
  • 1 cup chopped green pepper
  • 3/4 cup chopped onion
  • 2 cans (8 ounces each) tomato sauce
