I agree with several ideas here. I start with beef 75-80% lean, pressed as little as possible when shaping, brush the grill grid with olive oil and just sea salt and fresh ground 5pepper blend.
Top it with Bacon-Onion Butter
( 3 strips bacon cut into 1/4" pieces, 1 small sweet onion chopped into small pieces cooked in a skillet, cooled and blend in a food processor wit 1 1/2 sticks of butter and 1 tsp Dijon mustard)
Then the toppings of your choice
or
Ground turkey with a small piece of brie cheese in the center, topped with 1/4 thick slices of grilled onions and grilled Granny Smith apples :rockin:
