This super-easy vegetarian homemade potato soup topped with slowly melting cheddar cheese, green onions, and fresh chopped parsley is a potato soup that the whole family can eat. And, with little more than potatoes, onion, and garlic, it's also a great way to stretch your family's meal budget. However, this soup is probably best served as a light lunch alongside a fresh green salad, as it's not really a full meal in itself. With the cheese and green onions, this soup may remind you of stuffed potato skins. It's a low-sodium soup since the only salt added is to taste at the end, but check the ingredients of your vegetable broth if you're watching your salt intake. In addition, this vegetarian soup recipe is also gluten-free (as long as you use a vegetable broth that is gluten-free).
