Peel the strings from the snow peas. Thickly slice the shiitake mushrooms (about 5 mm thick).
You could remove the raw taste of snow peas by boiling water in a saucepan over high heat with a pinch of salt and blanch the snow peas for 30-60 seconds. Then drain and shock the peas in cold water. Drain again and then set aside.
Melt the butter in the frying pan, stir-fry Step 1. Once vegetables soften, add soy sauce. Sprinkle with umami seasoning to taste.
