Cut the onions in a food processor and process until finely chopped.
Place the lamb, lemon peel, spices, parsley and onion in half a large bowl, and season with the spices
Use your hands to mix the mixture until everything is very well combined
Heat the oil in a large skillet or casserole with a lid, then add the remaining onion, ginger, pepper and saffron.
Braise the meat for about 5 minutes or until the onions soften and start to take a golden color
Add in the lemon juice, stock, tomato paste and olives, then bring to a boil.
Add the meat chops, then reduce the heat, cover the cooking pot and cook for 20 minutes, turning the meat a few times. Remove the lid, then add the coriander and lemon slices, and tuck them between the meat chops.
Add in the potatoes, chopped into chunks and cook uncovered for another 14 minutes, until the liquid thickens up a bit.
Once the Tagine gets the thickness you want, remove from the heat
Serve and enjoy your Tagine hot with fresh dry bread or couscous.
