     1/2  large         green bell pepper -- chopped
     1/2  large         red bell pepper -- chopped
     1/2  pound         fresh mushrooms -- thinly sliced
   1      28 oz jar     favorite spaghetti sauce
  12      ounces        uncooked noodles -- (up to 16 oz)

   6      ounces        sliced pepperoni -- cut in quarters

Preparation:

Brown ground beef with the onions and peppers. When just done, add mushrooms and cook for about 1 minute more. Drain fat. Cook noodles until al dente. You do not want the noodles to be soft. Add spaghetti sauce and simmer until bubbly. Remove from heat. Add noodles and mix well. In crock pot, put a layer of the noodle mixture, cheeses and pepperoni. Repeat layers. Cook on high for 30 minutes and then on low for 1 to 2 hours. This recipe tastes like a piece of pizza in a bowl. Delicious!
