Lived off the Canadian version of MREs for 2 weeks when I was in Haiti after the earthquake. Definitely not a fan. One of the things that always impressed me about the Canadian lunch ones is they had a chocolate bar (candy bar for the Americans) in them. It was 30+ C degrees during the day and as long as the chocolate bars stayed in the sealed packaging they were solid but but the moment you opened the packaging the chocolate would melt in 5 minutes. Not sure, what black magic made it possible to chocolate solid in 30 degree C weather.
