I loved the flavor of this but my sauce never did thicken up...I let it simmer for 25 mins it did reduce down. Not sure what I did wrong but I enjoyed the spiciness of the mustard's. I used tenderloins and cooked them on the George Foreman grill. Thanks for posting!
This sauce is excellent....the only problem was that there wasn't enough of it! I would reduce the cooking time on the sauce a bit, as I ended up with very little sauce and had to add more broth and mustard to get enough to cover the chicken. So if you half the recipe, go ahead and make all the sauce....you won't regret it! Thanks for sharing this wonderful recipe!
