Creating the Mustard Sauce:
The star of this dish is the flavorful mustard sauce that coats the chicken breasts. To make the sauce, combine Dijon mustard, whole-grain mustard, honey, minced garlic, and a pinch of dried herbs, such as thyme or rosemary. Mix well to incorporate all the ingredients and set it aside. The combination of the two mustards adds complexity and depth to the dish, while the touch of honey balances out the flavors.
