Add a little olive oil to the pot and heat. Add onions, soup vegetables and broccoli. Deglaze with water and pour until vegetables are covered. Simmer for about 20 minutes.
Blend with a hand blender until a creamy mixture is formed. Pour in the remaining water. Simmer for 10 minutes and then pass through a sieve. Add the cream and season to taste with salt, pepper and broth.
