When I'm out alone, I try to keep it as simple as possible. One of my go-to's is Zataran's jambalaya mix. Boil mix with water and cut sausage,... add a little beer and done! Nice high carb meal right there.
I also enjoy bratwurst links cooked in a bath of beer (Yuengling preferred) and maybe a few onions, in a hoagie toasted over the fire.
Another easy one is a big honkin steak and green beans. Boil the beans with some simple seasoning, throw the steak on a hot skillet, season with salt only after cooking.
I find my camp meals increase in complexity exponentially when the wife comes along. I mean that as a good thing. Her meals are excellent.
I'll have to get the wife to write up some of her meals... but they are all essentially home recipes made ever-so-slightly simpler (normally she will do some prep work at home, like creating her own spice mix before-hand, etc).
Here's a kabob meal she did a while back (on the old grill - anyone interested in taking it off my hands - maybe at TECORE?):
Here are two more recent examples of her work in progress (from the trip out west - newer stove in use):
