Instructions

1. Cook large shells pasta according to package directions. Once cooked, separate and place on parchment paper on counter. Set aside.
2. While pasta is cooking, brown Italian sausage in a large skillet. Once browned, drain grease and return meat to skillet. Add in spinach, butter and onion. Saute for about 2 minutes.
3. Add in salt, pepper, garlic salt, worcestershire, oregano, and hot sauce. Mix until well combined.
4. Fold in parmesan cheese and 2 cup mozzarella cheese.
5. Using a large spoon, stuff each shell with sausage mixture, until all shells are stuffed. Place shells in ziploc bag and freeze until ready to use. When ready to cook, follow step 6 below.
6. When ready to bake, pour about 2 cup of Prego sauce in bottom of baking dish. Choose a dish size that will fit the number of shells you are going to be cooking. For my family, we each eat about 2-3 shells per meal. On top of sauce, add shells, then more sauce, if desired. Cover dish with foil and bake for 45 minutes in a 350F oven. Remove foil and add remaining 2 cup cheese. Bake an additional 5-15 minutes, until sauce on bottom is bubbly and mixture inside shells is fully heated, and cheese is melted.
