Miso (red miso is my favorite)
Chili sauce (love Sriracha)
Green leafy things (like kale and chard)
It is so very easy to make a hearty satisfying soup of miso, chili sauce, green things, and maybe some rice noodles and a whipped egg.
Miso is also good spread on crackers or toast, kind of like Vegemite.
Miso makes a great broth, and a great base for just about any stew or pot roast.
(and it keeps for about 3 years in the fridge, though a jar never lasts me that long)
Not sure if it's really "healthful" or not, but it adds a world of taste to many things!
