Street Food

Somewhere in the Jordaan district we have bought at a kiosk this waffle with strawberries for our kids. I guess it is a better option than deep fried unrecognizable stuff from a wall. What is your favourite Dutch snack ? A smoked sausage from Hema ? Fries with pinda sauce (patat met pindasaus) ? Oliebollen during Christmas ? Herring ? Mine is deep fried cod. Or patat as a good second place - small size and no sauce, please.
