We sat down and figured out a 2 week meal plan complete with a grocery list and posted it on our site. We even shopped the grocery list so we'd have a price for the items.  Now keep in mind it's just a guideline and our tastes may differ from yours, but it may give you some ideas on meal planning while camping.

My grocery bill for two weeks is around $120 and I am by myself and don't buy anywhere near as much as you do.
