Whisk together the sauce ingredients - ginger, garlic, soy sauce, fish sauce, miso and sesame oil in a bowl.
Heat the vegetable oil in a wok or frying pan over medium heat. Add the kangaroo fillet and cook till medium rare - 3 to 5 minutes per side. Move to a cutting board to rest.
While the meat is resting, reheat the wok or frying pan to medium heat and add the snow peas, broccoli, bok choy, capsicum, bean sprouts and zucchini; cook and stir until the vegetables are softened. Pour the sauce into the pan and allow to simmer 5 minutes.
While the vegetables simmer, thinly slice the kangaroo. Stir into the vegetables and serve immediately.
Absolutely delicious! All my family members gave this 5 stars. I served it on basmati rice. Hint: rinse the snow peas in boiling water, then in cold water and dry before using - it brings out the flavour - 24 Aug 2009
