In a small bowl, whisk together the gochujang, miso paste, soy sauce, maple syrup, garlic powder, and ginger powder with one tablespoon of water until the sauce is smooth.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Place the Gardein chik'n filets in the pan and sear for 4 to 5 minutes per side until they are golden brown and heated through.
Pour half of the prepared gochujang sauce over the filets in the pan, turning them frequently to coat until the glaze becomes sticky and fragrant.
Remove the glazed filets from the pan and set them aside on a plate to rest.
In the same skillet, add the chopped kimchi and sauté for 2 minutes to release its juices and deepen the flavor.
Add the cooked jasmine rice and chopped baby bok choy to the skillet, stirring in the remaining sauce to combine.
Stir-fry the mixture for 3 to 4 minutes until the rice is slightly crispy and the bok choy is tender-crisp.
Slice the glazed filets into thick strips and serve them immediately over the warm kimchi rice.
