Excellent recipe. My husband loves this meal. The only change I would make is to use 2 cans of cream of mushroom soup instead of the chicken. Both hubby and I didnt care for the recipe when I used the cream of chicken (didnt taste like salisbury steak). Added chopped onion to the mixture for added flavor and use ground SIRLOIN--it's the best. This was Great! I have never had Salisbury Steak with the sour cream, I have always made it with "regular" gravy with lots of onions (and sometimes mushrooms) in it. This is now a new thing at our house. We did use Greek yogurt being careful to just add a little at a time to the not too hot pan) instead of sour cream and low fat burger.
