Seaweed & Tofu Soup
Be sure not to overheat the miso or its beneficial bacteria would be destroyed. Seaweeds have natural glutamate, so I use the soaking water in the soup for natural flavor. Seasoned rice vinegar or mirin contain sugars, as an alternate to adding more sugar.
Pros: Good ingredients, and could use chicken or seafood instead of steak.
Cons: See above for hints.
