Is there any sort of portable oven, grill, or whatever, that you could use that is simply like buy it once & use it forever without paying another cent? Something where you don't need electricity, or have to refill the gas, or replace anything, or pay for anything else. I just want a no hassle, easy, long lasting, portable camping oven. Does such a thing exist or am I doomed!? PS I know fire would be one solution, but anything beside that.

I love to BBQ and we are planning a family camping trip. I want a small portable camping grill. I know, I know, cook over the fire, and we will, but I also want to cook on a grill too. The trip is 5 days. Thanks for your suggestions!
