This slow-cooker turkey soup recipe is perfect for lunches or soup suppers. The recipe contains ground turkey, vegetables, tomato sauce, and italian seasonings. The lean meat makes it relatively light and the vegetables and some basic dried herbs and great flavor. It's also very easy to put together and cooks for 6 to 8 hours in the slow cooker with no supervision needed. The recipe calls for beef bouillon and boiling water, but a good, low sodium or unsalted beef broth would be an even better choice. Just remember to taste and add salt, as needed.
