Also, we like to BBQ generally at home (gas, but the principles are the same), and a lot of that can translate to cooking on wood too.
Get a grate/grill, and do meat (steak, burgers, sausages, pork or lamb chops, ribs, chicken joints, fillets of fish, skewers of prawns etc) on that.
Do skewers of vegetables, or use a tin foil tray to cook them smaller and looser. Or wrap in tin foil packets - either mixed or individual (mushrooms are great, or mixed medditeranean style veg like peppers, onion, garlic, mushrooms, courgette and cherry tomatoes).
Corn on the cob straight on the grill.
Spinach leaves wilted in a pan.
Actually, look for ideas for scout camp cooking - they do lots on fires and make it easy for teenagers to do themselves.
You could even learn to cook a cake in an orange or an egg in a potato!
