Add the fennel seeds, coriander seeds, and black peppercorns to a spice grinder and freshly grind. Set aside.
In a food processor, add the onion and mince. Place the minced onion on a big paper towel (the towel will help absorb some of the water that’s released from the onion). Set aside for now.
Next, add the ground meat to the food processor.
In a bowl, combine minced meat, garlic, ginger, thai bird chili, freshly ground spices, salt, cilantro, mint and ghee.
Mix in the onions.
Grease your hands with a little ghee, grab a handful of meat and roll it into the shape of a sausage - slide in skewer.
Turn your grill on and cook over medium heat until no longer pink.
Serve with grilled vegetables.
