I love doing potatoes in the oven this way. They don't take too long and go well with lots of dishes-especially fish and chicken. The liquid will dry out during the cooking - that's the idea - but add a little more towards the end if needed. I made them to go with the Mediterranean Lemon Chicken recipe from this site.
Preheat oven to 200 degrees C. Boil water in a small saucepan then add the cubed potatoes and cook for about 7 minutes-till parboiled. Drain, reserving some of the cooking water. Place the potatoes in a baking dish.
Add the rest of the ingredients to a small jar and shake to combine, then pour the contents over the potatoes in the baking dish. Stir to mix the dressing well with the potatoes.
Cook for 20 minutes or till done, stirring the potatoes a couple of times to prevent sticking. Add some of the cooking water if the liquid dries out and the potatoes still need more time.
