A good accompaniment to wine-marinated pork roast with Sauce Robert?

I think something with potatoes would work great, but on the other hand, I would like more vegetables with the pork. Perhaps baked potatoes and some vegetable salad? But what kind of salad? Perhaps some dumplings and salad? Or is there anything ''traditionally'' eaten with pork and Sauce Robert? I don't know and need your help. Thanks.
