Chop a carrot, an onion, and about 4 tomatoes. In a saucepan, put about 1 tbsp of olive oil, a little garlic and saute for a few seconds, add your chopped vegetables, stir for about a minute and add a no-salt chicken broth. Add herbs to your liking (oregano, thyme...) and boil over low heat until vegetables are cooked. Remove from heat and puree in a blender. Maybe add a little milk or cream for body. The more aromatics you put in, the more flavor and less salt needed. Be careful to remove Bay Leaves from soup mix prior to puree-ing.
