In a casserole pot add the rapeseed oil and cook the onion and garlic over a medium heat for a couple of minutes.
Add the fennel and potatoes and continue cooking until the fennel begins to soften, stir in the flour then pour in the white wine and cook for a couple of minutes before adding the vegetable stock and orange juice and zest. Turn the heat down and simmer.
Brown the lamb chops in a little rapeseed oil in a hot pan then transfer to the pot. Add a little more vegetable stock if required and simmer away until the potatoes are tender. Finish with the chopped parsley just before serving. Great with some spring greens on the side.
