Preheat the barbecue to medium heat. When the grill is hot, clean it and put on the duck sausages.
Grill for 10 minutes, turning a few times.
Remove the duck sausages from the grill and set aside for 5 minutes, loosely covered with a sheet of aluminum foil.
Use the handle of a wooden spoon to press down the doughy inside of each piece of baguette to create an indentation just wide enough to hold a duck sausage.
With a knife, spread the ginger-poppy dijonnaise on the inside of the baguette pieces (toasted or not). Add the sausages and serve immediately with additional ginger-poppy dijonnaise and potato chips.
Put all the ingredients in a small, airtight container. Season with salt and pepper to taste, then mix well. Cover and keep in the refrigerator until ready to serve.
