For a richer flavor, try using a blend of ground chuck and ground sirloin. Feel free to experiment with different types of cheese, such as cheddar, Swiss, or provolone. If you prefer your eggs cooked harder, simply extend the cooking time slightly. Add a touch of spice with a dash of hot sauce or a sprinkle of red pepper flakes. Serve with your favorite burger sides, such as French fries, onion rings, or coleslaw.
