a propane grill is nice, or a charcle grill. but having some stones even just some concrete blocks setup into a small circle, that you can toss a "grill" to cook over a fire is pretty cool. nice spot to burn leaves and like, (not garbage), but serves for a cooking area. open a can of beans, vegetables, etc... and toss can on the grill and let the stuff warm up right in the can. having some allunium foil. to wrap other foods in to cock on grill helps a lot.
my mom found a "tripod" grill that raises / lowers with a chain, it kinda of a pain holding the grill as ya move food around. but allows you to adjust height and in that heat going to the food. it all folds up into a little package. nice for setting a couple small logs out for a fire, and letting them burn down some, and then toss it over the fire to cook with.
ya don't need much wood, say 3 to 4 logs 4" to 6" in size. cooks a big meal. being able to lower/raise the grill, lets ya adjust things as things burn down. if you have a ring made out some rocks. to hold the logs, it cooks much better. (focusing heat upwards) vs letting heat blow out the side via wind.

having a wood burning stove, with actual cooking top, to put a couple pans on is also awesome. i have seen a lot of 55 gallon metal drum wood stoves. but most of them all have round tops, a little piece of metal and a little bit more welding, for a flat surface on top. and away ya go with warming some food up / cooking food.

i have not done it, but you should be able to hook up a smaller vent-less wall heater (setup for LPS / propane), to a standard propane 20lbs tank (tanks for cooking grills) for heating a room or like in a pinch. ya don't need the 110v fan or anything.
