I recently got stranded in my car for a few days due to a confluence of events that can be charitably called a "clusterfuck". Thankfully I keep a large amount of canned fish, condiments, and crackers in my trunk at all times. Here are the things I ate during this time of living off nothing but fish in my trunk.
Chicken of the Sea smoked canned salmon, I added soy sauce and wasabi powder. Very delicious, would reccomend.
Patagonia canned mussels. Absolutely fucking disgusting. I normally like Patagonia stuff but this was gross. Maybe had gone bad?
King Oscar sardines in tomato sauce: pretty good but wish I had some vinegar based hot sauce. That is now remedied and I have multiple bottles of Louisiana and El Yucateco in my trunk now.
New Brunswick lemon pepper kippers: one of my go-tos for a quick meal. Mainly because they're cheap as dirt but I like them.
Still have about 50 cans/tins of fish in my trunk left. Always recommend it as an emergency food supply if you get stranded.
