1. In a bowl, mix ground beef, egg, breadcrumbs, Worcestershire sauce, ketchup, and mayonnaise until well combined.
2. Divide the mixture into 2 equal portions and shape into patties.
3. Cook the patties on a grill or skillet over medium heat until browned and cooked through, about 4-5 minutes per side.
4. While the patties cook, slice the avocado, tomato, and onion. Tear the lettuce leaves.
5. Toast the burger buns. Assemble the burger with the patty, avocado, gorgonzola cheese, tomato, onion, and lettuce.
6. Serve immediately.
7. Check that the ground meat reaches 71°C (160°F) throughout before serving.
