Place pork roast on a roasting rack in shallow pan. In a small bowl, combine the mustard, soy sauce, garlic, onion, rosemary and olive oil. Spread mixture over the entire roast. Roast, uncovered, at 350ºF for about 1 ¾ hours. Coat with any extra onion-mustard mixture during cooking. When the pork is done, slice and serve.

Good served with oven-roasted potatoes or spicy rice, green beans and a tossed salad with vinaigrette dressing.
