I have a few different rigs depending on how Im camping, from simple solo to the whole dang family.
On my two burner Coleman stove I have a griddle that fits perfectly, I can do a whole breakfast on it. I have a few Dutch ovens, like pictured above, that I can use for roasts, stews, bread, pies and cake. I have a large stock pot for stews and pasta, its a bit too large to fit on the Coleman stove so think about your heat source before you find your pots wont fit the stove you plan on using, in my case it doesnt matter I use the big stock pot on my brazier or over the fire.
Also a sauce pan that will hold two quarts or better for sides or to cook up quick stuff for the kids, cooking rice, beans or whatever it can be real handy. Some kind of fry pan, cast iron is always good, though most of this type of cooking I use the griddle.
I use a spatula, long tongs, wooden spoons, a long handled fork, can opener, copper pot scrubber and the regular flat ware. You can pick up a couple ¼ hard wood dowels at the hardware store and let the kids decorate them the way they choose, drill a small hole in one end for a lanyard for beads or whatever and sharpen the other end so they can roast stuff like marshmallows and hotdogs over the fire, soak the sharp end in water to keep from burning. I got this idea from a friends kids who are in the girl scouts.
Not related to this discussion but still a very cool idea for kids camping, also from these girl scouts, is each kid has a clean new white paint bucket from the hardware store or pickle bucket from a restaurant, 3 to 5 gallons with a snap on lit. They can take their extra stuff and as much as can fit in the bucket, it will keep their junk dry and serves as a seat when sitting around the fire. They are required to keep their stuff clean and in the bucket, each kid responsible for their plate, cup, utensils, tooth brush etc. you get the idea.
