Method

1. Heat half the oil in a large non-stick frying pan over high heat. Add one-third of the beef. Stir-fry for 2 mins or until browned. Transfer to a bowl. Repeat, in 2 more batches, with remaining beef.
2. Heat the remaining oil in the pan. Add the onion, baby broccoli and asparagus. Stir-fry for 5 mins or until just tender. Return the beef to the pan with the teriyaki sauce and walnuts. Stir-fry for 1-2 mins or until the sauce boils and thickens slightly.
3. Divide the rice and stir-fry among serving bowls. Serve immediately.
