In a large bowl, use clean hands to mix the bison meat and spices together until well-seasoned.
Form four patties, each weighing 4 ounces, 3 inches in diameter, and ½ inch thick.
Make a dimple in the center of each patty.
Preheat a grill, a grill pan, or a dual-contact electric grill over medium-high heat.
Spray or brush the grill surfaces with oil.
For medium doneness, grill the burgers for about 4 minutes on each side or a total of 4 minutes on a dual-contact grill.
Serve the burgers immediately.
