Greek Salad with Potatoes

Boychild loved this. OMG. He's never eaten Greek Salad before and professed to not like feta but he ate this. And had the leftovers in his lunch the next day. Wonders wil never cease it appears...

For 3-4 portions you need:
1/2 pack new potatoes, jersey royals if you can stretch to them ;-)
1 pack chilli olives
1 pack feta. crumbled into 1cm cubes
2 peppers, cut into chunks
2 red onions, cut into 8ths
2 tomatoes, cut into 8ths and then in half again (so roughly chopped...)
2 tbsp olive oil plus more for roasting
salt and pepper
large handful of fresh oregano, finely chopped
juice of 1 lemon

Cook the potatoes. Toss the peppers and onions in a little olive oil and season. Roast in a hot oven for about 10 mins till tender. Place the tomatoes, olives, olive oil, lemon juice, oregano and feta in a bowl. Add the peppers and onions once cooked. Drain the potatoes and cut in half if large. Add to the bowl. Mix and serve.
