In a large bowl add in your ground beef. Then in a medium bowl add minced onion, parsley, onion powder, garlic salt, celery seed, paprika & cayenne pepper. Whisk together in the bowl & set aside.

Next pour the Worcester sauce over the meat. Then sprinkle in the seasoning mixture. Then with your hands mix to combine seasoning well with the meat.

After cut your 3 Swiss cheese slices into bite sized pieces and then mix the cheese into the meat as well until fully incorporated.

With your grill on medium heat, cook each side for 3-4 minutes. 7 minutes on medium heat typically results in burger cooked medium, so plan accordingly to your preference.

When they have 1 minute left to cook, add the cheese on top if you would like to, for it to melt. Then start to layer your burger! I love to just do one bottom bun and add ketchup first, lettuce on top of the ketchup, burger, then pickled onions (RECIPE ABOVE-- a must make!), avocado and then croutons!

Enjoy what ever way you prefer!
