This recipe is courtesy of nutritionist Karin Adoni, and comes from her cookbook Clean Diet by Karin Adoni Company. These tacos are made with Portobello mushrooms instead of tortillas for added nutrition and flavor! Not only do these turkey tacos have all the traditional toppings but also a dollop of homemade guacamole. Note: This recipe requires 2 baking sheets for 7-10 servings.
