Thoroughly clean the pumpkin with a brush under running water to remove any dirt. Cut into small dice (without the rind) and set aside.
Peel and finely chop the onions and ginger.
In a saucepan, fry the onions and ginger with a drizzle of olive oil for a few minutes. Then add the diced pumpkin, salt and pepper. Leave to cook for a few minutes, add the vegetable stock and cover. Simmer for 20 minutes.
When the soup is almost done simmering, deep fry the ravioles for 30 seconds.
Once the pumpkin is soft, blend the vegetables and stock until smooth.
Pour the soup into bowls and top with the deep-fried Saint Jean ravioles.
