Natto is fermented soy beans and is often eaten for breakfast in Japan.  It is gooey and slimy, and also notoriously smelly, but it’s a nutritious and healthy food loved by a lot of Japanese people.

Natto is almost always eaten over rice.  It is extremely simple to prepare: you mix Natto with soy sauce or Mentsuyu and stir vigorously until forming sticky goo around the beans.  Then pour it over hot rice.  You can add toppings like chopped green onions and Japanese mustard, but basically that’s it.  There can’t be an easier breakfast than this.  Natto has a lot of nutrients like vitamin B, K, protein, fiber, calcium, etc.  Natto also contains its own enzyme good for preventing blood clots, so they say.
