I havent had anything too crazy the craziest things have been raisins and saltines at the same time and ketchup on a cucumber sandwhich... I have a couple friends though that craved some pretty wild stuff sliced strawberries in balsamic vinegar ( like cereal with milk) and the other one constantly craved dill pickles dipped in buttercream cake frosting....
I haven't had anything too crazy either. A hard boiled egg on a bagel with cream cheese has been the most consistent thing that always sounds good.
Peanut butter and salt and vinegar chips sounds amazing!
My strangest i guess is just cream cheese, added to anything, My pb sandwich, and type of pasta dish, and ive mixed it w honey and put on crackers.
