Add wine and chicken broth, cover, and simmer 7 minutes. Turn chicken, and simmer until meat pulls easily from bone, about 7 minutes more.03Transfer chicken from skillet to plate. Add remaining garlic, shallots and herbs, olives, escarole and lemon juice to skillet. Sprinkle with salt and pepper, increase heat to medium-high, and cover. Steam escarole until it wilts, about 5 minutes.04Return chicken to skillet on top of escarole. Add butter, increase heat to high, and simmer until butter melts and sauce has emulsified slightly. (If sauce appears thin, transfer escarole and chicken to warm platter, then boil sauce until it has reached a pleasing consistency.) Taste to correct seasoning. Serve immediately.
