Thinly chop the green onions and set aside.
In a microwave safe bowl, add in the bean sprouts. Layer the thinly sliced pork over the bean sprouts. Layer the pork so it does not overlap with each other.
Swirl in sake and lightly cover with a plastic wrap/wrap. Microwave for 2 minutes.
After checking that the pork are cooked, swirl in ponzu sauce.
Follow package instructions and cook the noodles. While waiting for the noodles to cook, prepare the soup in a bowl. Once the noodles are cooked, drain well and place the noodles in the soup bowl.
Slide down the pork and bean sprouts from Step 3 over the noodles. To finish, top with chopped green onions. Enjoy!
