Vegan Vegan Holidays Vegan Thanksgiving Vegan Thanksgiving Main Dish Sweet Potato Hash Stuffed Portobello Mushrooms 5.0 (3) 3 Reviews Diced sweet potato, bell peppers and apples make a vegan stuffing inspired by the flavors of sausage. To add that savory flavor, we use poultry seasoning (don't worry, there's no actual poultry in it!). Piled into portobello mushroom caps, it creates a beautiful and filling plant-based main dish—perfect for the holidays.
