Make the seasoning paste. Combine the tamari, miso paste and sesame oil with about 3 tablespoons of water in a small cup and whisk together until smooth. Set aside.
Serve the dish immediately. You can garnish it with some sesame seeds, chopped nuts and/or chilli flakes. Add some extra protein too if you like (e.g. chicken or fish).
*I usually use brown rice miso paste when making this dish. Miso paste tends to vary in strength, so the amount of 1 tablespoon may need to be adjusted depending on the intensity of your miso paste. Don't be afraid to add a little extra if you feel like your fried rice isn't punchy enough.
