Cook noodles according to packet instructions, including capsicum with the noodles. Drain noodles, refresh and set aside.
Score the duck breast with a sharp knife and season. Add duck breasts to a cold frying pan, skin side down and cook for 5-8 minutes or until fat renders and skin is crisp. Transfer to a baking tray, skin side up, and roast for 8-10 minutes for medium-rare or until cooked to your liking. Loosely cover with foil and rest for 5 minutes.
Divide noodles between plates. Slice duck and place on top, then add plum sauce, garnish with green onions.
