Crock Pot Deviled Swiss Steak

I have been making this for years. It's another family favorite.

In a large plastic bag , combine the flour , mustard , salt and pepper.

Add steaks and shake to coat.

In a large skillet , brown steaks on both sides in butter.

Transfer to crock pot.

Top with onion.

In a bowl , combine the tomatoes , worcestershire sauce and brown sugar.

Pour mixture over meat and onion.

Cover and cook on low for 6-8 hours or until meat is tender.
