campfire cooking

Hello all id like some help if anyone can offer it would be greatly appriciated. im going camping in a couple of weeks (not in a teardrop unfortenatly), and all i will really have to cook in/on is 2 surplus army ammo cans (http://www.therangerdigest.com/Tips%20Tricks/32%20ammo%20can%20bbq/32%20ammo%20can%20bbq.html) so i was wondering if anybody had any healthy recipies that i could cook on these. Im already going to be cooking burgers, fries, and coffee, so i was hoping for something a little more healthy.
Thanks
Thanks
