After leaving her marriage, Lyz Lenz found herself with stretches of time on her own. "Every day I was alone, I had to ask myself, What do I want to eat? The question seemed impossible," she says. For her Substack, she talked to Margaret Eby, who is working on a book about eating alone. "Margaret helped me understand how what we eat when we eat alone can help us become the purest expression of ourselves — in all our dirtbag glory," Lenz says.
