Preheat oven to 400F

Meanwhile, place tomatoes on the roasting tray with the potatoes and roast along with the beef. Remove from oven when beef is done, or when tomatoes and potatoes are tender. Cover to keep warm.
Meanwhile, steam carrots, broccoli and zucchini until just tender, about 10 minutes.
Serve sliced beef with potato and vegetables on a large serving platter, accompanied with sauce.
