Melt a knob of butter (oil will do too)

Chop the onion quite finely

Fry in the butter on medium heat for about 5 minutes until it becomes clear

Meanwhile chop a courgette into small chunks

If using mushrooms, slice and add them with the courgettes

Fry for another 5-10 minutes until the courgette browns slightly

Tear up some leftover chicken into bit size strips. I always make this with leftovers from a roast.

Stir in the chicken. This doesn't need to cook so go straight to the next step

Measure out 1/2 a pint of milk (full fat or semi skimmed)

Add a level dessert spoon of cornflour and mix well.

Pour this into the pan and keep stirring....

It will thicken in a few seconds

Add a tsp of bouillon powder or 1/2 a stockcube, and 1 1/2 dessertspoons of soy sauce. Stir through.

Add a large handful of frozen peas

Simmer very low for 5 minutes to cook the peas.

Serve on rice with extra soy sauce on the side
