Another very easy lunchbox idea. I didn't put the watercress in but I would imagine it owuld add a lovely peppery flavour.
Jazzy Smoked Mackerel Potato Salad (from Jazzy Potato)
100g green beans, cut in half
3 tsp horseradish sauce
2 tbsp natural yoghurt
1 tsp red wine vinegar
1 pack smoked mackerel
Large handful watercress
Cook the potatoes in a pan of boiling water. Add the green beans 3 mins before the cooking time is over.
While they are cooking mix together the horseradish, yoghurt and vinegar and season. Break up the mackerel fillets into bite sized chunks.
When the potatoes and beans are cooked, drain, tip into a large bowl, top with the mackerel and drizzle over the dressing. Toss well and place on a bed of watercress.
