This is one "meaty" vegetarian stew, thanks to the pumpkin purée, potatoes, lentils, and smorgasbord of vegetables. Garnish each bowl of soup with a little grated cheese — maybe Parmigiano-Reggiano or Asiago. Or, add a dollop of sour cream, yogurt, or crème fraîche.

Heat the olive oil over medium-high heat in a large stockpot. Add the garlic, leeks, celery, carrots, and potatoes and sauté until the leeks begin to soften.
Add the tomatoes, pumpkin, vegetable stock, oregano, cumin, and paprika. Bring to a simmer and continue to cook until the potatoes are tender, about 10 minutes.
Add the lentils, white beans, green beans, red peppers, and sage. Return to a simmer and continue to cook another 10 minutes. Serve hot.
