- Combine ingredients for slaw in a medium mixing bowl and stir to combine. Cover and refrigerate for 12-24 hours.
- Add ingredients for Asian glaze in a saucepan over medium heat and bring to a boil. Whisk to dissolve brown sugar. Turn heat down to medium-low and simmer for 20-25 minutes, until sauce has reduced and sticks to the back of a spoon. Transfer sauce into a small bowl and cool at room temperature for 1 hour to thicken further.
- Heat grill to 350ºF and lightly grease with cooking oil. Add sausages and grill for 8-10 minutes per side or until internal temperature reaches 160ºF. Spoon slaw onto buns and add a sausage to each. Drizzle with Asian glaze and enjoy.
