For those following a vegan diet, this mushroom soup recipe is a great option. It uses plant-based ingredients to create a creamy and flavorful soup without any animal products. Start by sautéing onions, garlic, and mushrooms until they are tender and golden. Add vegetable broth, soy milk, and nutritional yeast for a cheesy flavor. Let it simmer until the flavors meld together, then blend the soup until smooth and creamy. Serve it with a sprinkle of fresh parsley and a drizzle of olive oil for added freshness.
