I cooked this last week and it was so fast and really delicious.
I stir fried 3 larger cilantro roots, one medium sized leek and one apple (everything sliced) with a bit of oil, a table spoon of miso and a little salt. Meanwhile I cooked the pasta (store bought but vegan) and I fried some lightly salted tofu. I mixed everything in the wok. Maybe not the healthiest thing, but really tasty.
