Boil broth, add chopped shallot and pumpkin to it. Salt to taste and cook over medium heat until vegetables are cooked.
Remove cooked pumpkin from the broth and put them in a blender. Add coconut milk and lime juice. Mix until smooth. If you like more liquid soups, add some broth.
Serve hot by adding a little olive oil directly to the bowl. Sprinkle with pepper.
