Preheat oven to 350°F.
Remove stem from bok choy. Divide stalks, rinse and set aside.
Press tofu, if needed, to remove some of the moisture. Cut tofu into multiple chicken strip like pieces.
Place tofu pieces on parchment on a baking sheet in a single layer. Coat both sides of tofu with ½ of the sesame oil, soy sauce, and black pepper.
Tightly cover the baking sheet with aluminum foil and bake for 20 minutes.
Remove foil, flip tofu and push to one side. Add bok choy to pan. Coat bok choy with remaining sesame oil, soy sauce, hot pepper oil and salt.
Bake tufo and bok choy uncovered for 15 minutes until tofu is browned and bok choy is wilted.
