I'm so jealous that you're going camping, jitterbug!! Hope you have a lot of fun!
I agree with the chili suggestion. Another great camping meal (that's really impressive) is to make a potroast in a dutch oven. DH does this all the time with his friends and they're always impressed. We also use it to make lasagna, cornbread, peach upside-down cake, etc.
Dutch oven cooking is totally the way to go... super easy and impressive!
