Classic Spanish Burger with a Twist

Method

1. In a bowl, mix ground beef, egg, Worcestershire sauce, and a pinch of salt and pepper until combined.
2. Divide the mixture into four equal portions and shape into patties.
3. Heat olive oil in a skillet over medium heat. Cook patties for 3-4 minutes per side until browned and cooked to desired doneness.
4. Toast the hamburger buns. Place a slice of cheese on the bottom half of each bun, then add a patty, lettuce, tomato, and a fried egg.
5. Top with the remaining bun half and serve immediately.
6. Check that the ground meat reaches 71°C (160°F) throughout before serving.
