INGREDIENTS:

2 chicken breasts
olive oil as needed
salt and pepper
1/4 onion, small diced
1 oz white wine
1 teaspoon Dijon mustard (I used whole grain)

DIRECTIONS:

Season both sides of chicken breasts with salt and pepper. In a large sauté pan, heat olive oil and add chicken. When golden brown turn over and sauté on the other side. When done, remove from pan and discard most fat. Tent to keep warm.

In the same sauté pan, add onions and sweat over high heat until lightly caramelized. Deglaze with white wine and reduce au sec. Add chicken stock, bring to boil and reduce over high heat to suace consistency. Mount with butter and swirl in the mustard. Serve over chicken with Skinny mashed and salad.
