We do a lot of foil pack meals where you throw in some meat, some veggies, some seasonings, and some canned soup -- either beef & barley or cream-of-something -- and let it cook in the fire. We also wrap potatoes in foil and cook them in the coals. Another good foil dinner is salmon with lemon slices and dill on it. Cook until it flakes--serve with rice.
We also have pie irons in which we make all kinds of things. You put the bread slices on the outside and fill the inside with a variety of things, like:
* pizza sauce, sausage, and cheese
* corned beef, sauerkraut, and thousand island dressing
* pie filling -- blueberry, cherry, or apple
* chicken a la king
We've done the big Mulligan Stew thing where everybody brings a meat or veggie. Throw it all into the pot and let it brew a few hours.
