I love developing recipes that work in many ways. For this recipe, you can double the tomato sauce and transfer half of it to an airtight container before you stir in the pasta and sausage. The tomato sauce can be frozen for up to 3 months and used for other meals during the week, such as a quick pasta dish, chicken Parmesan or eggs in purgatory. This dish also keeps on giving, because if you have leftovers, you can freeze the remainder in individual portions for up to 3 months. When ready to eat, defrost in the refrigerator overnight and reheat until warmed through in an oven at 300 degrees F or microwave on a microwave-safe dish using a low setting.
