Tempeh is made from soybeans left whole (unlike its cousin, tofu). And the result is a food that tastes better than tofu and has a denser, sometimes even crunchy texture. In short, this is a food you should try urgently, even if you are not vegan.
This dish can be eaten as an appetizer or as a main course with a nice seasonal salad. It will surprise you with its mixture of flavours and you will see that the apple mixes well with salty flavours (and just as well in a salad of seasonal raw vegetables).
