Mix the meat with the spices, divide into 4 equal parts, and form them into balls. Place them in the fridge for 20 minutes to chill.
Prepare the Kamado BONO grill, light the charcoal, and place the cast iron griddle on top. Wait for the temperature to reach 180-200°C.
Adjust both the top and bottom air vents to maintain a consistent temperature.
Add a little butter and olive oil onto the cast iron surface, sprinkle with garlic and herbs, then place the patties on the griddle. Cook for 5 minutes on each side.
