In a large skillet over medium high heat, add the olive oil. Once hot, add the diced onions and cook for 3-4 minutes until softened, stirring continuously.
Add the crushed garlic, and cook for a further minute or so, then add the minced lamb.
Cook for a minute, breaking apart any clumps of meat with a wooden spoon, then add all the spices (seven spice or all spice, cinnamon, salt and black pepper). Continue cooking, a good 6-8 minutes until lamb is all cooked through and brown with no pink bits remaining. Keep stirring and breaking apart clumps of meat throughought- you can even use a potato masher to break the meat apart a little.
If desired, drain any extra fat. Taste the mince and adjust for seasoning.
*The same technique and ingredients are used for either beef or lamb mince, so use whichever meat you most prefer.
