Macaroni and cheese serves as the perfect comfort food for families on a budget. But you're not stuck with macaroni. Pasta and cheese is just as good as macaroni and cheese, so boil up a pot of farfalle, fusilli or another favorite pasta. As soon as the noodles are done, drain the water and mix in milk and your shredded cheese of choice. Toss in whatever veggies you have on hand, from frozen broccoli to chopped onions or peppers, then add sliced hot dogs or leftover chicken or sausage for extra protein. Place the dish in the oven and allow it to bake until the cheese is melted and bubbly. Too busy to use the oven? Try a no-bake, slow cooker version of this dish for when you just want to toss something in a pot have have it come out delicious.
