This site has some awesome camping dinner ideas. My favorites are always the foil packs. Everyone can put together their own and as long as it's completely sealed it's easy to cook. Will have to try some of these this summer.
Ice Cream in a Bag This is SOOO easy… and delicious! In a small Ziplock bag, put: 1/2 C. half and half (milk works too) 1 Tbps. sugar 1 tsp. vanilla Insert that bag into a larger, one gallon Ziplock filled with ice and salt. Shake the bag for five minutes. Kids love that part! Then, remove the smaller bag which should have turned into ice cream. I did this in elem school and have been looking every where for it!
