supper-spaghetti

One of the great cheap dinners is spaghetti. You can use 1/2 lb of hamburger ($1.25), a jar a spaghetti sauce ($2.00) and 1/2 package of noodles ($0.40). Throw in a can of vegetable ($0.60) and some bread and butter and you have the entire meal for under $5.00.
A great side for this (that you could use for more than one meal) is pasta salad. There are many variations of pasta salad but the one I like is rainbow rotini ($1.25) mixed with cheap Italian dressing ($1.25) and I cut up a few black olives and sometimes some onion.
