01 - Cook rice according to package directions until tender. Fluff with a fork and keep warm until assembly.
02 - Heat sesame oil in a large skillet or wok over medium heat. Add greens and sauté until just wilted, about 2 minutes. Stir in soy sauce and sesame seeds. Remove from heat and set aside.
03 - In the same skillet, add vegetable oil and heat over medium-high. Add sliced mushrooms and cook, stirring occasionally, until golden and softened, about 5–7 minutes.
04 - Add garlic and ginger to the mushrooms, cooking for 1 minute until fragrant.
05 - Stir in soy sauce, maple syrup, rice vinegar, and water. When bubbling, add the cornstarch slurry. Cook, stirring constantly, until sauce thickens and coats the mushrooms, about 2–3 minutes. Finish with toasted sesame oil.
06 - Divide warm rice among four bowls. Top with teriyaki mushrooms and sesame greens. Garnish with spring onions, carrot, avocado, extra sesame seeds, and lime wedges if desired.
