Cook bacon slices until crisp then drain on a paper towel lined plate.
Drain all but 1 tbsp bacon grease then add chopped onions and cook until softened, about 10 minutes.
Add a swirl of olive oil and add the mushrooms to the onions.
Cook for another 5 minutes or until mushrooms have darkened and softened.
Season with salt and pepper and remove from heat.
Form the bison into 4 round patties.
Season how you like. I used seasoning salt, ground black pepper, and garlic powder.
Heat a heavy skillet (I use a cast iron pan) over med high, add a swirl of vegetable oil and place all 4 patties in the pan.
Cook for a few minutes until a nice crust forms on one side. Flip and let cook for a minute then add a slice of cheese to each patty and cover pan with a lid for a minute to steam until cheese melts.
While the burgers are cooking butter and toast your buns, then spread the inside of the top bun with honey mustard.
Heat a small skillet and cook each egg, one at a time, to over medium. Gently flipping over once. Remove from heat to a plate.
Add a ham slice and 2 bacon strips crosswise on each burger then remove with a spatula and place each patty on each bottom bun.
Top with a fried egg and a mound of sauteed mushrooms and onions, then the top bun.
Prepare to get messy! Dig in and let your taste buds have a party!
