Directions

1. Heat the oil in a skillet over medium heat. Cook the onions, stirring often, until golden-brown and tender, about 15 minutes. Remove from the skillet and set aside.
2. Mix the beef, salt and pepper in a medium bowl until combined. Shape the beef mixture into 4 evenly sized burgers. Cook the burgers for 7-9 minutes, flipping halfway through or until cooked to desired doneness. Top each burger with one slice of cheese and cook one minute longer.
3. To assemble the burgers, spread mayonnaise on the bottom half of the bun. Top with the burgers, bacon and top halves of buns. Serve with potato chips and enjoy!
