Chicken with Creamy Dijon Mustard Sauce

Living in rural Tuscany has its advantages - home fed chicken! So many of our dinners consist of chicken but to tell you the truth I had never thought of using mustard with it. So thanks to food52 I came up with a new recipe. I had guests for dinner and wanted to make a more elaborate dish so I chose to use only chicken thighs with a very velvety mustard sauce. I chose to cook the sauce in a French style using the classic method of using chicken stock and a little roux to give the sauce more smoothness. The sage and garlic gave it a really nice taste and I served it with mashed potatoes
