Nothing says family dinner like a big helping of homemade spaghetti and meatballs. Ground beef is one of the cheapest meats you can buy, and pasta's even cheaper. A bonus for the penny-pinching cook is that spaghetti is filling, delicious and feeds a lot of people. And it doesn't have to get boring because you can change the sauce (tomato, Alfredo, vodka) or the add-ins (ground meat, meatballs, broccoli, asparagus, peppers) based on what you have around the house -- making this an easy regular feature on the weekly menu. A simple salad and some garlic bread make this the kind of family dinner staple that will bring everyone to the table.
