Final answer:
In Norse mythology, Odin feeds the heroes in Valhalla with an endless supply of food from the resurrecting beast Sæhrímnir and an inexhaustible mead from the goat Heiðrún.
Step-by-step explanation:
The mythological tales from Norse mythology describe Valhalla as a majestic hall located in Asgard, where Odin houses the souls of heroes slain in battle, known as the Einherjar. The narratives from the Prose Edda, a collection of Norse poems and stories, portray Valhalla as a place of ongoing glory and feasting.
According to legend, these heroes are provided with an endless supply of food and drink, which comes from the magical beast Sæhrímnir. This beast is said to be cooked daily and is capable of being resurrected to provide an unending source of sustenance for the warriors. They are also served mead derived from the udders of the goat Heiðrún, which also supplies an inexhaustible amount of the beverage for the fallen heroes to enjoy.
