Tempeh has a nutty, earthy, and slightly mushroom-y flavor. It also tends to absorb the flavors of any food or sauce to which it is added, making it a versatile choice for many sorts of dishes, from chilis and stews to sandwiches and tacos. Some people may find the flavor of tempeh to be overpowering or even bitter if its not prepared well. However, when cooked properly, tempeh can be a delicious and healthy addition to any diet.
