Emergency Essentials has single-serving MRE's available. You aren't forced to buy a case at a time, and there are quite a few to choose from. Average price is about $2.50 each. I have about a dozen in my car kit.
Sneaky man. Got me all excited; it's just the entree portion! Bummer, but good at the same time. Honestly, for a short term, do I really need chiclets?
