A meal in a box and the "ageless oxygen absorber" This post is long overdue. Many months ago I got in touch with a company called Meal Kit Supply Canada, a distributor of prepackaged meals developed by the U.S. Military. The meals are warmed using a water-activated heating pack. I had reached out to the company early on in the series, and Stevi Hanson, vice president business development, had sent me a sample pack of their most popular meals. It seemed logical to wait for an actual emergency or outdoors experience to try them out.
