This ridiculously lovely noodle dish takes just minutes to put together and is by far my favourite emergency dinner (I almost always have cherry tomatoes on the side and miso and spring onions in the fridge). Having tried this dish variously with every type of noodle, I can confirm the best are bouncy, thick udon noodles. If you haven’t got pine nuts in, chopped salted peanuts are a great alternative topping.
