I also tour stoveless. I normally use dried fruit as a post ride snack -- although I might get a small packet of sweets if I feel like it. Other than that I normally go with fruit, salads etc. A small cooler bag inside the pannier is a great way of allowing fruit to last a couple of days if need be. That said, I like to get to a cafe or restaurant to sample some cooked food for one meal each day, but going a couple of days between them isn't a problem.
