We have a healthy stock of SPAM and canned ham, that we rotate through the kitchen, by using them in soups and stews and such. We also stock cans of chicken/turkey/ham/salamon, but these aren't as popular with the family so I don't stock as much.

Canned tuna is a staple day hike or quick meal around here. Plain tuna gets paired regularly with mayo and/or relish/pickles, celery, fresh herbs, nuts, or whatever other yummies we have on hand. The little flavoured tunas are a bit pricey but packed with flavour. My personal favourite it to add them to raman noodles, but they're also great in sandwiches, wraps and salads or on crackers. It's probably the most versatile canned meat our family uses.

I've been trying to recreate the flavours using plain tuna but frankly, it's a PITA right now, so I bite the bullet and buy a few cans of the good stuff every week. One or two for my day pack, and an equal number for the panty.
