Slice your onion as thin as you possibly can. You can try a sharp knife, but if you have a mandolin or potato peeler that works best.

Preheat your griddle to 400-450 degrees.

Place your burger balls on the griddle and sprinkle them with salt.

Place a golf ball sized pile of onions on each burger ball.

Smash down your burgers with a spatula or a press.

Cook for five minutes before flipping.

Flip it over and let the onions cook in the beef fat.

While the onions are cooking, top it with cheese and place the two buns on top of the cheese to steam. Place your top bun down first on the cheese.

After 3 or 4 minutes take your bottom bun off, slide your spatula under the onions and assemble the burger.

Serve with a side of pickle chips and enjoy!
