Its very easy, you first saute the onion and potato until soft in oil, then add the celery and carrots and keep sauteeing for about 20 min. then add chicken broth to cover the vegetables and let simmer for about 1 hour. Next, I strain out all the vegetables and puree in the food processor and add back to the chicken broth. Stir and add about 3 tablespoons each of onion powder and garlic powder, you may even want to add more. This is a delicious soup, especially in the winter. You can garnish with dill.
