Read food labels carefully for content and food use information. Some convenience food such as instant potato flakes, minced onion, non-fat dry milk, etc. are economical for one person. Take care not to buy more food than you can use. When comparing prices, figure cost per serving rather than cost per pound. Cuts of meat high in bone, fat or gristle are expensive sources of lean meat even if they are priced low.
Mixes can simplify food preparation, save time and energy.
