Addictive carbs and salt, dirt cheap, and healthy as shit. Also convenient and compatible with most dietary/ethical restrictions.
If you learn to like beans when you're 20 and throw it into an index fund, you'll have a modest retirement fund just on the money you saved (yes, I calculated it based on money saved and growth of the S&P).
