Warm potato, pea and tomato salad

A friend gave me this recipe some years back, but I can't find her version. I made the following from memory; it turned out just fine:

15-20 cherry tomatoes halved
8 oz frozen peas (fresh will of course be fine, just cook for less time)
half a tin of anchovies (about 3) roughly chopped
2 tbsp olive oil
6-8 new potatoes scraped, halved and boiled.
Bunch of mint chopped (have a feeling original recipe used basil)
1 tbsp balsamic vingegar
Black pepper (NO salt - the anchovies provide this)

Heat olive oil and lightly fry anchovies with peas until anchovies have 'melted' (about 15 mins)
Mix in with potatoes, tomatoes, mint, vinegar and season with pepper.
Serve!

A platter of this salad (the above does for two if served this way) topped with barbequed chicken and lamb goes down well and is also simple as nothing else is required to accompany it.

Otherwise the above quantities will easily serve 4 with other salads etc.
