Cut the onion and ginger root into very fine cubes. Squeeze the garlic clove and sauté everything in a little sunflower oil.
Wash, core and cut the pumpkin into pieces, add to the onion, ginger and garlic.
Pour the vegetable stock so that the pumpkin is covered and let it simmer. When the pumpkin is almost done, add 2-3 bananas. When everything is soft enough, puree the soup and stir in some sweet cream. Do not let the soup boil anymore!
