Place the lamb and beef into a large mixing bowl and add the garlic, paprika, cayenne, fennel, salt and pepper. Mix well until combined. Cover the bowl and refrigerate for at least two hours to marinate.

Take about ¼ to ½ cup of the meat mixture and shape it into a 3 inch kebab log. Place it onto a plate and repeat shaping the remaining kebabs. 

Place the grill or skillet on medium high heat and lightly brush with oil. Add as many kebabs that fit onto the grill or skillet and cook until the kebabs have grill marks and are cooked through, about 3-5 minutes on each side. 

Serve hot.
