I cook a bit on mine, i found you need to create an air gap between pot and stove, otherwise the bottom of the pot gets to hot and burns the food.
I use a standard ceramic casserole dish with lid, then put some steel/metal bars under it to lift an inch, it slows down the cooking also, as direct will cook quite quickly if your fire is high.
jacket spuds cook quickly in the stove also, double wrap and place to one side, best to put a brick on one side of the stove and sit the spud on that so its not direct on coals, keep checking and turning.
I warm pies also, just sit them on foil and then again on bars to create a gap, go a couple of inches and let the heat pass through the pie, can take a while though.
