73% Lean / 27% Fat Ground Beef, 10 lb Roll, Fresh, All Natural*

Too easy. I found a Walmart in that area. They sell this beef at $4.74 per pound, these eggs at 12 cents per egg and this milk at $3.10 per gallon. Each day, if you eat 1lb of the beef and 6 eggs and drink half a gallon of the milk, you will consume 3020 calories and only spend $7 on food. If you need more than that, you could, of course, eat more of that stuff, or buy some potatoes or something else low cost.
