You can make some pretty fucking gourmet stuff over a campfire. Lure him out to the woods with campfire eats.
I personally cannot. I am not that good a cook. Nor can I carry all it takes to cook and clean a big meal while in the wilderness strapped to my little scooter. Stirfried veggies from the store and other small bits and bobs are all I can manage while on the road, and even that's a struggle.
