Musnad Ahmad 32:816

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from 'Abd al-'Aziz ibn Suhayb, who said: I heard Anas ibn Malik saying: "The Messenger of Allah (may Allah bless him and grant him peace) did not hold a wedding feast for any of his wives that was greater — or better — than the feast he held for Zaynab." Thabit al-Bunani said: "And what did he serve at the feast?" He replied: "He fed them bread and meat until they left it."
