Take about 1 cup of spaghetti sauce and spread on the bottom of the pan with about 1 cup of the cheese. Add pasta shells. Once shells have completed cooking, drain and place them on paper towels to cool. Add 1 tablespoon of the meat mixture. Then add desired amount of Colby-Monterey Jack cheese.
Place shells on bottom of pan until the pan is full.
You can usually get six or seven across in one row. When the pan is full, pour spaghetti sauce over the shells. If you have leftover meat, pour it on top of sauce and then add cheese, covering the entire pan. Bake at 375 degrees for about 30 to 45 minutes. Cheese should melt completely.
