Shelf stable keto

Hey guys im in the military and they are sending me on a aircraft carrier for 2 weeks. And while food is provided at chow it isn't always keto friendly. The meals I can eat I will but what things can I bring with me to eat. I know things like tuna jerky nuts anything else that might be a life saver ? Also I know I'm gonna have a hard time reaching fats for the day any advise ? I won't have anything to refrigerate food with .
