• kosher salt
• 3 cups mashed potatoes
• 6 cups low-sodium chicken broth
• crisps or crackers (optional)
Directions
1. Heat the oil in a large pot over medium heat. Add the leeks, fennel pieces, and ¼ teaspoon salt. Cook, stirring occasionally, until soft, 8 to 10 minutes.
2. Add the mashed potatoes and broth and simmer over medium heat, stirring occasionally, until heated through, 4 to 6 minutes.
