What does the Grinch eat by himself?

In Dr. Seuss's "How the Grinch Stole Christmas," the Grinch eats a solitary meal of "roast beast" on Christmas Eve, reflecting his disdain for the festive celebrations of Whoville. His solitary dining illustrates his isolation and disconnection from the joy of the holiday season. Ultimately, his character transformation leads him to embrace the spirit of Christmas, moving beyond his lonely existence.
