Rinse the rice until the water runs clear. Put in a small saucepan with 250ml (1 cup) water, cover and bring to a simmer over medium heat. Reduce the heat to low and cook for 12 mins or until tender and the water is absorbed. Turn off the heat and stand, covered, for at least 5 mins.
Step 2 — Prep ingredients
Meanwhile, trim the beans and cut into short lengths. Halve the zucchini lengthwise and thinly slice on an angle. Peel and finely grate the ginger.
Step 3 — Make stir-fry sauce
Combine the ginger, oyster sauce, mirin, 1 tbs soy sauce, 3 tsp white vinegar and 1 tbs water in a bowl.
Step 4 — Stir-fry pork
PORK STIR-FRY OPTION Separate the pork stir-fry. Heat 1 tbs oil in a large deep frypan over high heat. Stir-fry the pork for 2-3 mins until cooked through. Remove from the pan.
Step 5 — Stir-fry vegetables
Heat 2 tsp oil in the same pan. Stir-fry the beans and zucchini for 1 min. Add the stir-fry sauce and cook, stirring, for 1 min or until the vegetables are just tender.
Step 6 — Get ready to serve
Add the pork and any resting juices to the vegetable stir-fry and cook, stirring, for 30 secs or until heated through. Fluff the rice with a fork. Divide the rice and stir-fry among bowls. Scatter with the sesame seeds to serve.
