Steam or boil the broccoli for 3-4 mins until tender. Drain and run under cold water.
Heat 2 tsp of the oil in a non-stick wok or large frying pan and toss the beef strips in cornflour. When the oil is hot, fry the beef for 1-2 mins to brown, then put to one side.
Heat the remaining oil in the pan, then toss in the peppers and fry for 2 mins. Add the ginger, garlic, chilli and 3 spring onions, and cook for 1 min more, taking care not to burn the garlic. Add the orange juice, honey, rice vinegar and soy, and bubble down briefly before stirring in the broccoli, beef and orange segments. Heat through, then sprinkle with the remaining chopped spring onion. Serve with rice or noodles.
