fish soup

i made a fish soup today.  it tasted pretty good.  here's the recipe:

chicken stock, already prepared by my mom. 
tomatoes, cooked already a week or two ago, by my mom.  just cooked a bunch in oil with medium heat, until most of the juice came out. 
Hot pepper sauce, prepared by my mom.

Yellow onion, sauted in low heat.  I'd prefer to cook longer, but it turned out good. 
Garlic, crushed, chopped, added to sauted onion. 
Celery, a stalk chopped fine, added with one wedged carrot into onion and garlic. 
added, 龍利魚.
added tomatoes, stock, chinese cooking rice wine, miso, hot pepper sauce.
then, added 豆腐, 或著油豆腐. 

simmer for 20 minutes. 

no salt or pepper required.
