What was the Sunnah of Prophet Muhammad (peace be upon him) regarding meal times?

The guidance of the Prophet (peace be upon him) regarding food was that he would not reject what was available nor seek what was not. Whatever good food was presented to him, he would eat it, unless he disliked it. Most of his food was placed on the ground on a mat, and he would eat with his three fingers and lick them when he finished. He would not eat while reclining. He would mention Allah's name at the beginning of his meal and praise Him at the end with various supplications. And when he finished his meal, he would lick his fingers.
