Cut the pork and kimchi into bite-sized pieces. (There have also been times when I don't cut either). Since it's difficult to heat tofu, if you want to cut down on cooking time, then microwave it a bit to warm it up.
Cook the pork. When it changes color, add the kimchi and then the tofu. While cooking, break the tofu into bite-sized pieces.
Mix it all together so that everything is combined. Once everything is cooked through, it's done.
Story Behind this Recipe
Whenever I begin dieting, I end up preparing this somewhat diet-unfriendly dish...
If you're worried about the excess moisture in the tofu ruining the dish, drain it. Since the pork is cooked in sesame oil, it should have a bit of flavor, but add soy sauce, sake, sugar, mirin, etc. I try not to add anything else since I eat this while I'm on diet.
