Apartment Prepper: Prepping On A Budget

In "Prepping on a Ramen Budget: How to Stockpile Food for Under $20 a Month" from Apartment Prepper, the author notes:

With just $20 a month, your focus should be on affordable, long-lasting, and high-calorie foods. Prioritize staples like:

•     Rice
•     Beans
•     Pasta
•     Canned goods
•     Oats
•     Powdered milk
•     Peanut butter
•     Cooking oil
•     Salt and sugar
•     Shelf-stable proteins (tuna, Spam, lentils, dried beans)

These items provide the most calories and nutrients per dollar and have long shelf lives. 

The author goes on to set out some strategies for stretching your dollars and a schedule of what and how much to buy each month over a four month cycle that will provide you with a stockpile of a month's worth of food in that four months (I presume for a single person). The author then offers additional worthy advice, so be sure to read the whole thing.
