Mix all the sauce ingredients (ponzu sauce, sesame oil, chili oil, grated ginger, grated garlic, and white sesame seeds) in a bowl.

Cut the chives into 3cm pieces using kitchen scissors and place them in a microwave-safe dish. Add the bean sprouts and mix them together, shaping them into a dome.

Spread the pork belly slices over the dome, wrapping it completely. Sprinkle with salt and pepper. Cover loosely with plastic wrap and microwave at 600W for about 5 minutes until the pork is cooked.
