Mix the ground beef, seasoning salt, Worcestershire, garlic powder, and black pepper in a large bowl until combined. Form into 8 patties and set aside.
Set a large non-stick frying pan on the stove over medium-high heat. Add the burger patties, working in batches if needed, and cook for 3 minutes, flip, and cook for an additional 3 minutes. Test the temperature and cook longer if desired (mine turned out medium-well). During the last minute of cooking, add a slice of cheddar cheese to the top of each patty to melt.
Add one patty to each burger bun and assemble with lettuce, tomato, onion, two pickles, and desired amount of special sauce. Enjoy immediately.
