I made this today and it waa delicious. Gyoza you can buy at the supermarket freezer section (use veg ones). Qua extra veg in the dish I varied the vegetables (bimi) but other than that more or less stuck to the recipe. I also used readymade curry paste which I usually make myself so this way it was actually very quick and easy.
I also made baked rice and green beans both in the oven to be efficient with the energy and in fact the sauce is delicious with beans!
