  • 750g pack baby new potatoes
  • 2 x 230g packs purple sprouting broccoli
  • 450g pack green beans, topped but not tailed
  • 1 tbsp extra virgin olive oil
  • 1 shallot, finely chopped
  • ½ lemon, for squeezing

For the dressing

  • ½ x 20g pack tarragon, leaves chopped
  • 2 tbsp white wine vinegar
  • 2 tsp Dijon mustard
  • 145ml extra virgin olive oil
  • 3 tbsp double cream
  • Pinch sugar


  1. Make the dressing. Put the tarragon, vinegar, mustard and seasoning into a bowl. Using a fork to whisk, gradually add the extra virgin olive oil. Stir in 2 tbsp water and the cream, then add a pinch of sugar. Taste to see what you need to adjust. It might need a little more sugar or mustard. Set aside.

  2. Cook all the vegetables until tender. I boil the potatoes (about 20-25 minutes) and steam the broccoli and beans together, in a separate pan or over the potatoes for the last 5-10 minutes. Heat the olive oil in a small frying pan and sauté the shallot until soft but not coloured. Add a squeeze of lemon and season.

  3. Pat the potatoes, beans and broccoli dry with a clean tea towel (otherwise the moisture clings to them, diluting the dressing). Mix the vegetables together in a warm bowl, season, then add the shallots and dressing. Gently turn everything over and serve with the chicken.
