instead of Kale I sliced zucchini and roasted that as well. Pre-roasted all vegetables then put them in to warm up at the end. Did the rice in a hot skillet with sesame oil instead. And make gojuchang SAUCE as mentioned in the NYT comments instead of using the chili paste on its own! awesome recipe. Served with quick pickled cucumbers.
For the gochuchang, you want to make a sauce (don't use the straight paste!):
2 to 3 tablespoons gochujang paste
1½ tablespoons rice vinegar
1 tablespoon sesame oil
1 tablespoon maple syrup
You can also add a splash of soy sauce.
