Stroopwafels are very common snacks in the Netherlands. This is made from two thin layers of baked dough with a caramel syrup filling in the middle. They are recommended to be placed above a hot drink for a minute to make them even more delicious. They are regularly sold in the street, so they are not hard to find.
Dutch vegetable soup with meatballs. This is very good. A soup my mother-in-law made. There is also a homemade tomato soup with tiny meatballs that is delicious. We make it often in the summer with garden tomatoes.
