Oklahoma Onion Burger. OK, sure, it doesn't look all that great, but it is a fantastic 12 paper towel burger. Just look at the pool of grease, Russian dressing and melty cheese! Smashed patties on the griddle, throw a ton of sliced onion on top, let the burger crust up, then flip so the onion steams, add American cheese to the crust, let steam/griddle until melted. While all this is happening, butter a sesame seed bun and griddle that. BUT, flip the top so the seasame seeds toast a little. Add Russian dressing. Have a roll of paper towels on-hand.
