Divide 1 1/3 pounds of 80/20 ground beef into four 1/3 pound patties. Then slice a whole yellow onion into 1/8-1/4 inch slices.

Then place a slice of onion down on a flat surface, add the 1/3 pound of ground beef and then top with another slice of onion. Then push the onion down to form a patty that has the onion embedded in it.

Preheat your grill to medium/high heat.

Season both sides of the burger with seasoned salt.

Place the burger over the heat and grill until you start to see juices bubbling up around the top piece of onion. Then Flip.

Grill until the burger is finished to your liking. I would give you a specific amount of time, but it varies based on burger thickness, grill temp and desired doneness. I like my burgers medium so I usually cook for another 4 minutes after the flip. Once again, this varies based on the burger and grill.

Remove and serve with your favorite toppings.
