This is a quick and easy camping meal. I've used dried garlic, chilli and ginger to make it easy to transport to the campsite, but if making this at home, you can use fresh.
Prepare the vegetables and pack together in a ziplock bag. Measure out the chilli flakes, ground ginger and garlic powder into a small container. Measure the miso paste into a separate container.
To cook:
Bring the water to a boil in a large saucepan. Add the udon noodles and simmer for 2 minutes.
Add the remaining ingredients (except for the pak choi) and simmer for 4 minutes.
