2 Tbsp soy sauce
3 Tbsp Mirin
2 Tbsp Sake
2 chicken thighs or 1 chicken breast (cut into bite size pieces)
4 green onions (thinly and diagonally cut)

Cut green onions thinly and diagonally. Set aside some greener parts for garnish.
Heat Dashi to a boil. Add salt, soy sauce, Mirin, Sake to Dashi, then chicken.
Skim fat and other particles from the surface of the soup if there are any. Add Udon to the soup and let it simmer for 2-3 minutes.
Put in most of green onions including white parts, then turn off heat right away.
