Tempeh is a powerhouse food, but it often gets overshadowed by its more popular cousin, tofu. But how much do you actually know about this plant-based protein? Here's everything you need to know about tempeh, so you can start adding this meat alternative to your diet. Tempeh is made from soybeans. To make tempeh, soybeans are cooked and fermented then packed into a brick-like cake. Tempeh is very high in fiber, offering more than a quarter of our daily fiber needs in one serving. In addition to protein, fiber, and probiotics, tempeh is also a great source of vitamins and minerals. Tempeh has a distinct tang and nutty flavor and it absorbs the flavor of ingredients around it. It is extremely versatile, acting as a delicious replacement for bacon, ground beef, and even croutons.
