2 thick slices of soft white bread
1 tablespoon butter, softened
2 teaspoons mayonnaise
1 tablespoon chives, finely chopped
2 teaspoons hoisin sauce
1/8 teaspoon five spice powder
4 slices Swiss cheese
3/4 cup cooked duck, sliced thinly with crispy skin still on
4 thin cucumber slices
4 thin radish slices
Butter one side of each piece of bread with butter. In a small bowl combine the mayonnaise, chives, hoisin sauce, and five spice powder. Spread this mixture thinly over the other side of the bread.
Place one of the bread slices, butter-side down, into a skillet set over medium-low heat. Top with two slices of cheese, the duck, cucumber and radish slices. Lay two pieces of Swiss cheese over the duck and vegetables and place the other slice of bread, butter-side up, on top.
Cook the sandwich for about 5 minutes, just until the cheese begins to melt and the sandwich is browned on one side. Then gently flip and cook for another 3 or 4 minutes, until that side is also golden brown and the cheese on the other side has started to melt. Remove from heat and let sit for about 5 minutes before slicing and serving.
