Add the broth, potatoes, tomato paste, and liquid aminos. Bring to a boil, covered. Reduce the heat to medium low. Cover and cook for 25-30 minutes, stirring occasionally, until the carrots and potatoes are very tender. Add the canned beans, herbs and salt; cook for 5 minutes more. Stir in enough basil to taste. Finally, place 2 cups of the stew into a blender; process briefly. Add this mixture back into the stew pot. This thickens the stew. Stir in the chopped parsley at the very end.
