It depends on where we are & what type of camping we're doing. If we're traveling & sight seeing, then I like to have pre-cooked meals. It's nice to be able to warm something up and eat before midnight!
If we're camping... in one spot for several days...then I like to drag out the DO and charcoal. We have a tripod too that we use often too.
Many times, I'll just prepare extra of whatever I fix at home and freeze it to use. I've got 1/2 of a pork loin, Buffalo chicken strips, various stews & soups just waiting in the freezer for out next trip! I also use a crock pot a lot.
