the oil in a large pan, fry the onions for 5 mins until golden and
softened, then tip onto a plate. Add the chicken breasts, browning for a
few mins on each side, then stir in the balti paste, quinoa and onions.
Sizzle for a few mins, then pour in the tomatoes and stock and give
everything a good mix. Bubble for 25 mins until the quinoa is tender and
in the cashews and most of the coriander with some seasoning, then pile
into bowls and scatter over the rest of the coriander to serve.
