Salisbury Steaks with Onion Gravy

Cube steaks recently grown in popularity, because they are inexpensive and they cook very quickly in a skillet. I created this recipe one work night, when I was tired and hungry. The sauce turned out to be really flavorful, and the cooked onions gave a lot of extra flavor to this quick dinner. I served this over homemade mashed potatoes (though rice or egg noodles would work well. In less then 30 minutes, dinner was served. My husband loved it so much, that he requested it the very next night.
