01 - Cook the rice according to package instructions. Keep warm until ready to assemble.
02 - Steam the broccoli florets for 5–7 minutes until crisp-tender. Set aside.
03 - In a bowl, toss the tempeh cubes with 2 tbsp cornstarch until evenly coated.
04 - Heat 2 tbsp oil in a large nonstick skillet over medium-high heat. Add tempeh cubes and cook for 6–8 minutes, turning occasionally, until golden and crispy. Remove and set aside.
05 - In the same skillet, add soy sauce, maple syrup, rice vinegar, sesame oil, garlic, ginger, and water. Bring to a simmer.
06 - Stir in the cornstarch slurry, whisking until the sauce thickens and becomes glossy (about 2 minutes).
07 - Return the tempeh to the skillet, tossing to coat evenly in the sticky teriyaki sauce.
08 - Divide rice among four bowls. Top with teriyaki tempeh, steamed broccoli, avocado slices, sesame seeds, and spring onions. Serve immediately.
