When you run out of cooking ideas, try this one pot miso soup! You can use any ingredient you have, just chop it up and then cook in medium heat. Often I add dumplings too. Instead of miso, I also recommend water + sake for a lighter soup base. Recently I also tried tomato + water as base and add hotpot ingredients for the one pot meal. Quick and easy, and most importantly warm and yummy for a cold day!
