In a large bowl, combine the ground bison, shredded cheddar cheese, and salt.

Mix gently until all ingredients are just combined, being careful not to overwork the meat.

Divide the mixture into four equal portions and shape each into a patty about 3/4 inch thick.

Preheat a grill or skillet over medium-high heat.

Cook the patties for 4-5 minutes per side, or until they reach an internal temperature of 160°F (71°C).

Toast the hamburger buns if desired.

Serve immediately.
