It always amazes me that dad, who isn’t a patient man to begin with, and what little patience he had he lost raising six kids, will still make the effort to gently stuff dozens of pasta shells. Not to say there wasn’t any grumbling, but he knew the work was going to pay off, and it did. Jumbo pasta shells, stuffed with a mixture of Italian sausage, spinach, ricotta and Parmesan cheeses, surrounded by tomatoes and baked until bubbly, do you think there were any leftovers? Hah! No way. Add the sausage to the pan, breaking up the sausage into smaller bits. Lower the heat to medium. Cook sausage until cooked through, and no pink remains, about 5 minutes. Add the garlic and cook until fragrant, about 30 seconds to a minute more. Remove pan from heat. At this point you can make ahead, to freeze (up to four months) or refrigerate before cooking. (If freezing, cover with foil, then wrap with plastic wrap.) Remove foil and sprinkle with remaining Parmesan cheese, bake uncovered for 10 more minutes.
