If you would like to make your own salad dressing, whisk together 3 tbsp olive oil, 1 tbsp wine vinegar or lemon juice and 1 tsp Dijon or other mild mustard. Season to taste, then mix with the horseradish.
450g/1lb new potatoes, cut into bite-size pieces
3 smoked mackerel fillets, skinned
250g pack cooked beetroot
100g bag mixed salad leaves
2 celery sticks, finely sliced
50g/2oz walnut pieces
FOR THE DRESSING
6 tbsp bought good-quality salad dressing
2 tsp creamed horseradish sauce
Boil the potatoes for 12-15 mins until just tender. Meanwhile, flake the mackerel fillets into large pieces and cut the beetroot into bite-size chunks.
Drain the potatoes and cool slightly. Mix the salad dressing and horseradish sauce together in a salad bowl and season. Tip in the potatoes – they should still be warm.
Add the salad leaves, mackerel, beetroot, celery and walnuts, and toss gently. Serve with crusty bread.
