Cut the chicken breasts into 2cm pieces. Season with salt, pepper and sesame seeds.
Bring a large pan of salted water to the boil. Cut the broccoli into florets and blanch for 2 minutes in the boiling water then drain.
Peel and finely dice the red onion. Finely chop the chives.
Heat a wok to hot and add the groundnut oil. Add the chicken pieces to the pan and cook for 2 minutes. Add the broccoli and cook for a further 2 minutes before adding the chopped red onion. Deglaze the pan with soy sauce and add the sesame oil.
Serve immediately, sprinkling the chopped chives over the dish.
«Try marinating the chicken in the soy sauce and sesame oil for one hour. Drain well before cooking.»
