Pre-heat your griddle to medium-high heat. Add a tablespoon of olive oil to Blackstone. Add sliced sweet yellow onion to one heat zone on your Blackstone and toss in oil to caramelize for 4-5 mins.
Form the ground beef into 4 ounce meat balls. Place the meatballs on the griddle and smash thin. Add some Blackstone Steakhouse Seasoning over each patty and cook for 1-2 minutes each side.
Flip the burgers and add caramelized onions, Chili Cheese Fritos, BBQ Sauce and a slice of American Cheese.
