Either this: https://en.wikipedia.org/wiki/Linsen_mit_Sp%C3%A4tzle
Or the world famous: https://en.wikipedia.org/wiki/K%C3%A4sesp%C3%A4tzle (Okay... It probably not only origins in my area, but that shows how good it is)

I'm lazy so I'll just say poutine

Belgian cuisine is famous for the local monk beer, fries and cheeses. All three together will make you go through winter but also grow you fat! Haha! But some of these beers are very well worth tasting!
