This was my lunch yesterday.
Based on this recipe.
I used canned tuna, sauteed with soysauce, mirin, and a teeny pinch of sugar.
Green beans were used instead of the snowpeas, and cold soba with chilled dipping sauce instead of rice.I substituted the sake in the eggs (didn't have any) with a little mirin.
Whoops. Buckwheat Soba contain wheat (duh).
I ate it anyway...delicious!
