Snack and pølser

What do people eat on the go in Denmark? Pancakes? Kebabs? Well, sure but that is not the most typical option, which is pølser (hot dogs). How can you cook this monument of Danish cuisine yourself?
Well, very complex indeed ;-) You will need:
- Sausages
- Hot-dog rolls
- Danish style mustard not too strong and a little sweet
- Ketchup
- Grilled onions (can be bought already prepared, it's easier and it smells so bad when you cook it yourself, they are very strong those Danish!)
- Slices of pickled gherkins, "Russian" style
- Optional: chopped fresh onion. Sorry, we did not have any for the photo!
Preparation: Heat the sausage (possibly also the bread), open the bread lengthwise and place the sausage inside (and everything else...)
You will say: "Okay, but everything will fall when you eat it!". Well yes! That is the funny part!
Bon appétit!
