Cut the chicken into strips and toss in a bowl with the lime juice, garlic and a tablespoon of the olive oil.
Heat the remaining oil in a deep frying pan. Add the red onion and white wine and bring to a simmer.
Add the chicken, crumble in the stock cube and simmer for about ten minutes, or until the chicken is cooked through.
Add the cream and wholegrain mustard to the pan and continue to simmer for two minutes, until reduced and slightly thickened.
Add the chopped tarragon and stir through.
For the salad, mix together the chicory, carrot and chives. Add the oil, lemon juice and balsamic vinegar and toss thoroughly.
To serve, spoon the chicken on top of the salad and drizzle with the cream and mustard sauce.
