Wonderful recipe!! I love the beauty of the pinwheels served on the plate and the thyme really made this Chicken Cordon Bleu taste fabulous!!! I did cook these longer than 20 minutes, more like about 40 or 50 minutes to get to an internal temp. of 180 degrees F. The chicken was really moist and delicious wrapped with all the cheese and ham!! I kept with the French theme and served this with Haricots Verts With Shallots and Lemon and the meal was simply delicious!!! Thanks for this great recipe!!!
