HOW TO COOK SHELLS: Bring a large pot of salted water to the boil, add the pasta shells then follow package directions for cooking the shells (I cooked mine for 10 minutes). Drain, and then rinse the shells with cold water. Set aside on a baking sheet.

HOW TO MAKE FILLING: Heat a wide skillet over medium-high heat. Add the sausage and cook until browned, about 10 minutes. As the sausage cooks, use a wooden spoon to break the sausage up into small pieces in the pan.

Stir in the garlic, canned tomatoes and spinach. Cook until heated through and liquid reduced by half, about 2 minutes. Remove the pan from the heat then stir in the ricotta cheese. Taste for seasoning then adjust with salt and pepper to taste.

HOW TO STUFF SHELLS: Each shell is stuffed with a heaping tablespoon of the filling. You can stuff them on the baking sheet and then transfer them back to the pan to reheat. Spoon the remaining sauce over the shells and reheat for 5 minutes. They are ready to serve as is, sprinkled lightly with Parmesan cheese and parsley.
