There's at least a couple of places to purchase pickles in Disneyland. These are from the kiosk across from Geppetos in fantasyland. You'll find pickles at the market near the Jungle Cruise exit and at a kiosk in Tomorrowland too. They are not too pricey at abt $3.50, delicious and will fill you up without weighing you down. They are a must-eat snack for my kids on all our visits.
