A good quality chocolate bar and a jar of peanut butter.

I would go to China for some barbecue duck.

If you're OCD then follow this procedure:
- make a binder of food expiration and storage times from Internet sources.
- purchase a whiteboard from an office supply store and mount it in your kitchen (mine's 24"x36").
- every time you cook, open a package, or purchase fresh produce, write down what you have left and date it according to the above binder.
- scan the whiteboard weekly to see what item's expiration date is coming up so you can plan your meals.

I've saved over $300/month doing this.
