Savory Swiss Steak

1 1/2 pounds sirloin, trimmed of all visible fat 
1/4 cup flour 
2 teaspoons dry mustard 
1 teaspoon salt 
1/4 teaspoon pepper 
2 teaspoons butter (I actually use non-stick cooking spray for this)
1 onion, finely chopped 
2 carrots, peeled and grated 
2 stalks celery, finely chopped 
2 cups diced tomatoes (canned with liquid) 
2 tablespoons Worcestershire sauce 
1 tablespoon brown sugar 


Cut steak into 6 serving size portions. Coat with a mixture of flour, mustard, salt and pepper. 
Using a large frying pan, brown meat in half the butter. Transfer to crockpot. 
Heat remaining butter and oil in frying pan. Sauté onions, carrots and celery until glazed.
 Add tomatoes, Worcestershire and brown sugar. Heat, scraping up drippings. 
Pour over meat. Cover. 
Cook on low, 6 to 8 hours, or until tender. 
Serve meat with sauce spooned over. Sprinkle with parsley.
