New potato and tuna salad

Cook the potatoes in boiling water until tender , about 15 - 20 minutes.

Meanwhile , mix together the garlic , the parsley , lemon juice , zest and olive oil to make the dressing.

Drain the potatoes well , then put them into a salad bowl. Pour over the dressing and stir it through so that the flavours are soaked up by potatoes as they cool down.

Flake the tuna fish into chunks and add to the potatoes with the spring onions , cucumber and tomatoes. Toss together gently , then serve at once.
