This is probably not authentic Texan cuisine but it is really good, good for you and uses nacho cheese as a salad dressing! The nacho cheese is nut-free and the soaked sunflower seeds make a great creamy dressing like cashews do but at a fraction of the cost. Read all the directions before you start making this dish since the sweet potatoes have to go into the oven before the tempeh and the tempeh needs to marinate prior to baking. This dish is vegan. gluten-free and nut-free.
