There are various recipes that are all very good for stuff shells. One way to you can make stuffed shells is by first boiling your shells. While the shells are boiling get your ground beef, sausage, pepperoni, onions and peppers cooking. Add the desired seasonings to your ground beef as it is cooking. Once your ground beef and other items are completely cooked, drain and add to your spaghetti sauce. Take shells and drain the water from your pan. Now you will take each shell and fill them up with your spaghetti sauce mixture and place in a baking pan. Continue until all your shells are full. Next you can take some cheese or a variety of cheeses and sprinkle it over the shells. Place the shells in the oven for about 10 minutes, just long enough to melt your cheese.
