ground beef, onion, elbow macaroni, one can of spaghetti sauce(I use Hunt's Four Cheese- it's usually $1), 1 can of stewed tomatoes, sour cream and cheese.
Start your water boiling for the elbow macaroni. (I didn't put measurements on here, because I don't really use any. You kind of know how much to use for you own family.) While the elbow macaroni is cooking, cook your ground beef with one onion. After draining off any grease, add the can of spaghetti sauce and the can of stewed tomatoes. When the macaroni is done cooking and strained, add the sauce mixture. Then add about 2 tablespoons of sour cream and then grate a bunch of cheese over the top and stir it in so that it just kind of melts into it. Then you are done! It sounds like an unlikely combination, but it is so good and very "comfort food-y".
