Step 1

In a medium bowl, whisk together the apple cider vinegar, stone ground mustard, and sugar until well combined and sugar has dissolved.

Step 2

To the dressing bowl, add the shredded apples, Napa cabbage, and carrots. Toss the apple mixture with the dressing and set aside for 5 to 10 minutes while you grill the sausages.

Step 3

Heat a grill or grill pan over medium-high heat. Grill the chicken apple sausage for about 4 to 6 minutes until grilled and warm. Grill the buns on the cooler side of the grill for about 5 minutes until warm.

Step 4

Place a sausage in the bun, top with mustard apple slaw and garnish with chopped chives.
