Thai coconut soup is an easy and flavorful vegetarian and vegan soup to try, made with asian ingredients and a coconut milk base which is much different than the usual broth-based vegetable soups which are more common. The flavor comes from the deliciously spicy and fragrant combination of the thai ingredients: red chili peppers, ginger, lemongrass, and lime. This thai coconut soup recipe is both vegetarian and vegan. All of the ingredients are gluten-free, except for the vegetable broth, which may or may not be gluten-free. If you're buying vegetable broth, check the ingredients list, as many have additives which contain hidden gluten. Or, make your homemade vegetable broth, so you can be certain what's in it.
