In a skillet with butter sauté onion and peppers for about 5-8 minutes, until tender.
In a large bowl, mix together the bison meat with the A1 sauce, egg, bread crumbs, salt and pepper. Add the sautéed onions and bell pepper.
Mix until completely combined then evenly separate the meat mixture to four equal part. Form into patties.
Use a cast iron fry pan cook to desired doneness (120 F for rare, 130 F for medium rare and 160 F for well-done). Top with cheese and let the cheese melt for 1-2 minutes.
Remove the patties from the grill and place on plate. Butter the pretzel rolls and place in the hot pan to toast for about one minute. Place burgers on pretzel rolls and top with favorite toppings.
This is what Kerri had to say about her recipe:
I love A1 sauce and just want to taste it.
