Tempe is simply delicious and I am so happy to have made this discovery...I just hope I can get hold of it back in the UK! Vegetarian – often used instead of tofu and is much nicer in my opinion. Tempe is a traditional soybean product from Indonesia and is especially popular in Java. It is a fantastic source of protein, and in fact has a higher protein and vitamin content than tofu due to the fermentation process and the beans remaining whole. It can be used in a number of ways such as curry, steak, and stir-fried.
