Heat the oil in a large wok over a medium heat and add the duck. Stir fry for 3-4 minutes until sizzling.
Finely chop the spring onions. Chop the peppers. Add these to the wok and stir fry for another 30 seconds.
Add the rice and soy sauce. Cook for 5 minutes, stirring frequently, until warm.
Move the rice to one side of the pan, making a space for the eggs. Crack the eggs into a separate bowl and whisk, then pour into the gap you have made. Gently move the egg around until cooked, then stir to incorporate into the rice.
Cook for two more minutes, then serve immediately.
