01 - Rinse the rice under cold water until the water runs clear. Combine rice, water, and salt in a saucepan. Bring to a boil, reduce heat, cover, and simmer for 12–15 minutes until the water is absorbed. Remove from heat and let stand, covered, for 5 minutes.
02 - While the rice cooks, toss the beef slices with 1 tbsp soy sauce and cornstarch.
03 - In a small bowl, whisk together all sauce ingredients: soy sauce, oyster sauce, honey, sesame oil, garlic, ginger, and rice vinegar. Set aside.
04 - Heat vegetable oil in a large skillet or wok over medium-high heat. Add beef in a single layer and sear for 2–3 minutes until browned but still tender. Remove beef from the pan and set aside.
05 - In the same pan, add carrots, bell pepper, and sugar snap peas. Stir-fry for 2–3 minutes until just tender but still crisp.
06 - Return beef to the pan, add the sauce, and toss everything together for 1–2 minutes until heated through and well-coated.
07 - Fluff the cooked rice and divide it among four bowls. Top each with beef and vegetable mixture.
08 - Garnish with cucumber slices, spring onions, toasted sesame seeds, and fresh coriander if desired. Serve immediately.
