Mbh 12.243.1b

He should never eat twice between morning and evening, and should never summon his wife to bed except in her season. In his house, no Brahmana should be suffered to remain unfed or unworshipped. He should always worship such guests as are presenters of sacrificial offerings, as are cleansed by Vedic lore and observance of excellent vows, as are high-born and conversant with the scriptures, as are observers of the duties of their own order, as are self-restrained, mindful of all religious acts, and devoted to penances. The scriptures ordain that what is offered to the deities and the Pitris in sacrifices and religious rites is meant for the service of guests like these. In this mode of life the scriptures ordain that a share of the food (that is cooked) should be given unto every creature (irrespective of his birth or character), unto one, that is, who for the sake of show keeps his nails and beard, unto one who from pride displays what his own (religious) practices are, unto one who has improperly abandoned his sacred fire, and even unto one who has injured his preceptor. One leading a domestic mode of life should give (food) unto Brahmacharins and Sannyasins. The householder should every day become an eater of vighasa, and should every day eat amrita. Mixed with clarified butter, the remains of the food that is offered in sacrifices constitute amrita. That householder who eats after having fed (all relatives and) servants is said to eat vighasa. The food that remains after the servants have been fed is called vighasa, and that which is left after the presentation of sacrificial offerings is called amrita. One leading a domestic mode of life should be content with his own wedded wife. He should be self-restrained. He should avoid malice and subdue his senses.
