In a medium bowl, mix together the bison, 2 tablespoons of the hoisin sauce, salt, garlic and ginger.
Divide the meat into four portions and form each into a ½-inch thick patty.
Cook until the patties are cooked, with a bit of pink in the middle, 2 to 3 minutes per side.
Lightly toast the hamburger buns, spread 1 teaspoon hoisin sauce on each, top each with a cooked patty and ¼ of the slaw.
The Slaw:
Place the cabbage in a small bowl, then toss with rice vinegar, olive oil and chili garlic sauce.
