1. Preheat the oven to 450° F. It's important to get the oven nice and hot so that everything cooks evenly and develops a lovely caramelized texture.
2. In a square baking dish, mix the sesame oil, miso paste, tamari/soy sauce, ginger, garlic, honey, chili flakes, and green onions. Stir well until everything is combined, forming a delicious marinade.
3. Add the chicken to the marinade and toss it to fully coat. Make sure every piece of chicken is enveloped in that flavorful mixture.
4. Sprinkle the chicken with sesame seeds for added crunch and flavor. Then transfer the baking dish to the preheated oven and bake for 20 minutes. The chicken should be cooked through and deliciously glazed.
5. If you like your chicken with a bit of a caramelized finish, broil it for an additional 1 to 2 minutes. Keep a close eye on it during this time!
6. While the chicken bakes, prepare another baking sheet by rubbing it with olive oil. This will prevent the sweet potatoes and asparagus from sticking.
7. Add the sliced sweet potatoes and trimmed asparagus to the prepared baking sheet. Toss them with olive oil, salt, and black pepper. This will enhance their natural flavors, making them taste amazing.
8. Bake the vegetables for 15 minutes. After this time, toss them gently to ensure even cooking, then cook for an additional 5 minutes until they are crisp and tender.
9. Once everything is cooked, serve the chicken, sweet potatoes, and asparagus over bowls of coconut rice, which is a great complement to the savory dish.
