Tempeh ( pronounced tim-pay ) is a fermented, soy-based product. It is a high protein plant-based food, that tastes mildly nutty and tangy and has a lumpy mouth feel, like firmer cottage cheese. Tempeh makes a good beef substitution because of its hearty texture, its firmest and excellent absorption rate. It can withstand being sautéed , fried or grilled without crumbling.
