Thanks for posting. This is one of those situations where the gallon of milk could do you well. Maybe not whole but consider how one gallon is $3 per day on the expensive end of the price range for milk. That is $90 per month and contains 192 g carbohydrate and 128 g of protein for 1200-2400 calories depending on the fat content. Once protein is figured out it isn’t difficult to accumulate decent carbs (e.g. canned beans, whole grains, veggies etc) for $120 per month.
