Since no one has mentioned it yet:
Jalapeno Cheddar Pretzel, available at AK (Harambe Fruit Market stand, in the Africa area) and I've heard they are also available in the World Showcase at Epcot. So warm and savory, and pretty filling, too. If I picked two WDW treats to magically appear in front of me right now, it'd be one of these hot pretzels and a Dole Whip Float.
