This is a basic miso soup recipe from my Grandfather. Many different leftover items can be added; tofu, eggs, vegetables, cooked chicken or pork, somen/soba, or rice. The recipe calls for Ajinomoto (monosodium glutamate), I usually leave it out. I remember my Grandfather only using a dash of MSG, if you'd like to add it.
- Bring water to a boil; add dashinomoto and miso, stir until miso is dissolved. Add any extras if desired. Garnish with chopped green onions.
