Gently combine all ingredients with your fingers just until they are mixed. Over mixing will destroy the tenderness.
To form the patties, take the lid to a gallon jar or use mason jar ring. Line it with plastic wrap so it overhangs the edges. Place this on a kitchen scale and zero it. Then add the amount of meat you want to use gently press the meat flat.
Press an indentation into the middle of the patty. This will help your burger cook out flat. Set the burger / plastic wrap aside and keep using the lid and new wrap until you have four burgers.
Start with a clean, oiled grill at medium-high heat (375F). Leave the lid open while you cook. For additional help preventing sticking brush both sides of the hamburger patty with olive oil.
Grill 2-3 minutes on the first side before flipping for about two additional minutes. Salt patties as you go with seasoning salt or kosher salt.
Add cheese right after you flip the patties.
