Flash freeze the pork for 30 minutes so it is slightly firm. This will enable you to cut it very thin, without moving around so much. Prepare all the veggies. In Japan, they like to cut little designs in the mushroom tops!
Mix the Sukiyaki sauce in a bowl (or measuring pitcher) and set aside.
Heat a large skillet to medium-high. Add the oil, then pile the pork, tofu, noodles, and vegetables in the skillet, reserving the onion greens for later. Sear the meat and veggies for 1-2 minutes, then flip them over and sear another 1-2 minutes.
Add the sauce to the skillet. Allow the ingredients to cook down for 5-8 minutes, stirring occasionally until both the pork and the carrots are cooked through.
Remove the sukiyaki and serve over sticky rice (sushi-style rice) or as is. Sprinkle with the onion greens.
