Just what I was looking for! I lightened the recipe for my weight loss program by using ground turkey instead of meatballs (though they sound delicious), and substituted 2% milk for the cream, and non-fat yogurt for the sour cream and served over noodles or spinich. I offered sour cream on the side. I would also consider reducing the mustard to 2 teaspoons, though the family thought it was a winner to repeat as described! Thanks!
A big winner in our house! You know it's good when a 7 yr old "loves it". I didn't have any mushrooms or heavy cream on-hand, so I substituted some cream of mushroom. I added about a 1/4 c to the onions, after sauteing them for a min or two, and another 1/4 c to the broth mix. I used 2% milk since I didn't have the cream and added slightly more flour to thicken the sauce. I think next time I may go a little lighter on the Dijon though. Thanks for sharing your recipe! It's going in my collection.
