Belgium would like a word

Paprika chips are very popular, but I noticed you already used that for The Netherlands (Croky is a Belgian brand btw). An alternative would be Croky Hula Hoops or Croky Superfrites/Lays sticks. Also a staple is "Tuc" crackers by Lu, comes in different flavors (the cheese one is good).

edit: there are so many good sweet snacks/cookies I wouldn't know where to begin. Off the top of my head I would say speculoos (sold as biscoff in the US), Petit Écolier, Jules Destrooper butter crips, anything by Lotus bakeries (frangipane, zebrakoeken, mergpijpjes).

edit 2: not sure if this qualifies, but Royco minute soups are really nice and come in tons of different flavors. I might have to order a box if you make a Belgian one, I'm missing out on all that good stuff after moving to the US :)
