This recipe says cook the chicken at 400 for 12 minutes. At that heat the chicken was raw by the time it was done cooking. I ended up having to cook them for 40 minutes to achieve any sort of doneness. Not sure if they skipped steps on the recipe or what.
Chicken with Mustard & Leeks
From EatingWell: March/April 1993
A savory mustard coating keeps the chicken moist; threads of carrot and leek add color. Make it a meal: Garlic-Rosemary Mushrooms and roasted red potatoes.

easy and delicious. i added potatoes to the packets. veggies were crisp tender. dish was visually appealling also
this recipe was easy and delicous. I would say it takes 25 minutes to cook. make sure to use the tenderloine pieces as a whole breast might not cook fast.
