Make sure your steak is at room temperature. Combine all the rub ingredients and rub it all over both sides of the steak(s); let them sit for about 10 minutes.
Heat your grill, a cast iron skillet or grill pan over medium-high heat until it’s hot but not smoking. (If you don’t have cast iron, use a regular skillet and drizzle with canola oil.) Put the steak onto the grill or into the pan and cook for 4-5 minutes per side (2-3 minutes for bison steaks) for medium-rare. Let them rest, tented with foil so that they don't cool down, for 10 minutes before slicing.
