Season the chicken, coat with flour, then brown in olive oil. Finish in a 350-degree oven.
In the same pan, saute the onions and mushrooms in butter, then add the stock, wine, lemon juice, rind, and garlic and reduce by half. Melt 2 T butter into the sauce to finish.
Plate the chicken, dress with the sauce, garnish with the parsley and serve.
