I have some suggestions for motorcycle camp-cooking. The first, if you like Spam, is to look for the foil-wrapped single-slice-o-Spam they're selling now. Needs no refrigeration, provides enough meat for a hearty hot sandwich, and can be heated quickly in a tiny pan over a pocket stove. Or you can mix it in with your eggs in the morning. Or eat it cold. My second suggestion is to look on Ebay or similar sites for the self-contained aluminum one-man "mess kit" that the Boy Scouts used to sell. It provides a small pot with lid, a drinking/measuring cup, a plate and a folding-handle skillet in a package about the size of a canteen. Very handy. You might also consider an item sold by Civil War "sutlers" (merchants) called a "mucket." Available on the Net in pricey period tin or cheap modern stainless, it consists of a large mug/small bucket - hence the name - with a mug handle, a bail handle, and an attached hinged lid. You can cook in it, eat out of it, drink out of it, hang it on your belt and take it with you, and store your spare socks in it.
Enamel-covered steel with specks of contrasting color in it - sometimes called "speckleware" or "splatterware" - is designed for cooking and is often available in the camping aisle at big-box stores like Wal-Mart, or at yard sales. Just watch out for chipped or worn areas which can burn you and will rust through if left bare.
Yes, you can safely cook in a can. Many canned items are at least partially cooked in the can as part of the manufacturing process. That's how they get the same amount of pasta in every can of chicken noodle soup. If you're as frugal as I am (read "cheap"), you can even make a pot at home before your trip out of another -- slightly larger -- can. Put a coat-hanger-wire bail on it so you can pick it up when it's hot. You can store the can-o-dinner inside it and toss it after just one use if you want -- no clean-up! As a biker, you will want a folding military-style P-38 or P-51 can opener if you don't already have one.
Ride a couple miles for me while my leg finishes healing and I rebuild the fairing on my beloved Consuela!
And please...don't stomp the Spam!
