Do they have buffalo wings in a can
Frank's hot sauce and butter. Make anything taste like a buffalo wing
Seriously, it's not a bad idea to keep some flavor condiments on hand in the event of shtf. I would imagine you may be eating some not great food and anything you can do to flavor it up for more variety of to be more appealing would go a long way.
Ps-I also heard people who eat more spicy food are less likely to get sick. Doubt there is any evidence to back it up, but interesting to consider.
