• In a skillet cook the bacon to your preferred doneness. Set aside on a paper towel to catch the grease.

Caramelizing the onions

• Remove the grease and heat ¼ cup of butter over medium high heat. Add the sliced onions and cook until caramelized, about 10-15 minutes. Place the caramelized onions into a bowl and set aside.

Making the turkey burgers

• In a mixing bowl combine the eggs, mayonnaise, turkey, and breadcrumbs. Mix until everything is combined. Form into 4 equal sized patties.
• Heat the remaining butter in the skillet over medium high heat. Add all 4 of the patties to the pan and cook 3-4 minutes per side. Flip the burgers one more time and add the cheese, cook for another minute.

Assembly

• Spread the cranberry sauce on the bottom bun, add the burger, then top with bacon, and caramelized onions. Spread a little more cranberry sauce on the top bun.
