What's nicer then to slice up some nice veggies of the season, fry them in Olive oil until softened - add onions & garlic at the same time, a thumb-sized piece of Ginger, a few leaves of sage & thyme. Fill the pot up with 1 1/2 liters of good veggie or chicken stock. Let cook for about 40 minutes. Season with Salt & Pepper.
Use an Immersion blender to get the real creamy consistence of your soup and add a lug of sour cream. Season to Taste!
