Some good sounding recipes here. I won't give a recipe, but here are some ideas:
-Sounds like you are now planning on getting a grill. That is a good start. Propane works, but a charcoal grill always tastes better. There are plenty of small portable charcoal grills out there. You can grill almost anything you want. Peppers, zucchini, squash, asparagus, and corn are easy and particularly good grilled and don't necessarily need to be wrapped in aluminum foil. Always use olive oil on any veggies you will grill. For other ideas, there are tons of good websites and cookbooks out there for grilling, but it can be as simple as slapping down just about any cut of meat and it will be good (though a rub or marinade will make it better).
-Camp stove. If you don't have one, you really need to get one. A quality basic model without any bells and whistles will run about $50. You'll probably go through one $2 canister of propane in one or two weekend camping trips. You can do anything you can on your stove at home.
-A cast iron Dutch oven is a great addition to your camp kitchen. Get one with legs and you can cook with it quite easily in your campfire. You can buy a tripod and hang one without the legs, or you can get a grill top with legs to go over your fire. You can use the Dutch oven on your stove, but you will end up using a lot of propane for slow cooking (you may want a 5lb or 10lb propane canister if you do that).
With those three options (or really, any two of them) you can cook almost anything you would at home and variety will certainly not be an issue.
