Peel and chop onions and root vegetables. Clean and chop the cabbage, peppers and tomatoes.
Add water to the vegetables and cook in a pressure cooker at low temperature for about 15 minutes. Finally, season with soup seasoning and herbs de Provence. Bring to the boil again briefly, then leave to infuse for about 5 minutes with the lid closed.
Arrange the soup and serve.
