I found another package of Natto ( fermented beans ), some sliced beef, bell peppers, scallions.
Cooked beef, bell peppers and scallions in the pan and poured Mongolian barbecue sauce into it. Sprinkled little pepper.
For beans, I chopped Shiso ( Japanese basil ) and mixed into them and used sweet soy sauce which was attached to the package.
Fridge is getting lighter !
