Place the spinach, artichoke hearts, broth and alfredo sauce into your slow cooker. Cover and cook on LOW until the vegetables are tender, 4 to 6 hours. If you want a smoother soup, run your stick blender through it until you achieve the desired consistency. Or puree a cup or two in your blender and pour back into to the slow cooker. Turn the slow cooker to HIGH and add the pasta. Cover and cook until the pasta is done, 10 to 15 minutes more. Stir in the fresh lemon juice. Taste and add more salt and pepper as desired.
