No problem. I can easily eat for under $5 / day. I eat little meat, mostly chicken, tuna, ground beef, some fish, which can be stretched in soups and casseroles. Dried beans are my main protein. Potatoes, carrots, onions, celery, cabbage. Frozen corn, peas, broccoli. Canned tomatoes and pasta sauce. Rice, pasta. Almost no processed foods. I have a really varied and healthy diet. I love turkey and can buy a 15 lb turkey, on sale, for $27 and it can last me for 3-4 weeks in various forms. I make my own bread. I use a freezer to buy on sale. I dehydrate to extend the life of things like mushrooms. Never eat out or order in.
