Pre-heat the oven to 180 degrees C. Start by making your marinade by mixing the soy sauce, honey, and Chinese rice vinegar. You can marinade the fish with this a couple of hours before you plan to eat, but why make things tricky for yourself?
Create a little pocket for the fish out of tin foil (or baking parchment). Using an oven-proof dish, pop your foil in and create a little wrap. Put the fish in your wrap, cover in the marinade and grate your half a clove of garlic on top (omit if you don't like garlic).
Fold up your tin foil parcel so your fish is sealed. Pop it in the oven for ten minutes or until completely cooked through.
Meanwhile, chop your greens and sauteé with a teaspoon of vegetable or sesame oil for five minutes until cooked through. Season with salt and pepper and pop in a dish. Cook the rice or noodles if you're using.
Take the fish out the oven and lay on top of the greens. Cover with the marinade. Enjoy and pat yourself on the back for enjoying such an easy and healthy lunch.
