Have your choice of grill (charcoal, gas, indoor) preheated to medium before preparing your burgers.
Bring your bison out of the fridge about 10 to 15 minutes before shaping patties so the meat can warm slightly.
Add the bison to a bowl and sprinkle evenly with salt and pepper.
Using your hands, gently mix the seasonings in but do not over mix or mash the meat. Alternately, you can form patties and sprinkle each one with salt and pepper.
Form 6, 1/3 pound patties aobut 1 inch thick. If you'd like smaller burgers, you can do so, just know they will cook faster. If you'd like to brush them with a bit of olive oil on both sides before griling, do that now.
Grill on one side 4 minutes, turning once while cooking. Don't mash the patties or flip them a lot. Cook 4 minutes on the second side or until the patties reach about 150 degrees internally.
Allow the meat to rest, covered lightly with foil or a bowl for 10 minutes before serving.
