Barbecued Beef Strips

Slice steak 1/8-inch thick while partially frozen.

Brown in hot oil; stir frequently.

Add tomato sauce, mustard, brown sugar, Worcestershire sauce, water and sliced onion.

Cover and simmer for up to an hour, at least 30 minutes.

For a tangier barbecue sauce, stir in a little red wine vinegar or cider vinegar to taste before pouring over rice or noodles.
