Grind the first 8 ingredients to a paste, adding a little water if necessary (I use either a mortar and pestle to grind ingredients to a paste or my Magic Bullet machine).
Mix the meat and onion together and stir in the spice paste, chilli powder and salt. Add enough beaten egg to make a firm consistency and mix thoroughly. Set the mixture aside for 3 minutes to allow the egg to bind it together.
Divide the mixture into 12 equal portions. Using your hands, form each portion into a sausage shape to a length of about 4 inches. Arrange the kebabs on a grill pan or wire stand in a baking tray and cook them in a preheated 375 oven for 15-20 minutes, turning the kebabs to cook them evenly.
Serve with lemon slices. Enjoy!
