After about five mnutes from the start of the squash cooking, put the duck breasts on the plancha skin side down until nicely brown
Picture . Turn and cook for a three or four minutes and check the interior of the breast with a sharp knife. I like the duck to be pink but not rare and to be cut into thick slices say ¼ inch. Meanwhile put the squash into a serving dish, stir in the peas and keep warm
Picture and reheat the orange sauce.
