Iri dofu or iri doufu (炒り豆腐) is a simple, homely dish, real Japanese style 'mother's cooking'. Probably every Japanese home cook has his or her own recipe, but the base is plain tofu that is crumbled and then stirred around or gently stir fried (the iri 炒り part means that) until it resembles dry scrambled egg. In fact, it's rather like the tofu version of iri tamago, but with more flavor and texture.
Iri dofu recipes often contain meat (usually pork), dashi or both, but here I have kept it vegan (in keeping with our vegetarian theme for May). I have added umami by including chopped dried shiitake mushrooms, miso and soy sauce. Garlic chives and ginger also add to the flavor, while the sansho pepper (also known as sichuan pepper) adds spice.
The best way to eat this is to simply pile it onto rice. Of course it's perfect for a easy, healthy bento.
