Peel and cut the potatoes into wedges and place them in a bowl.
Whisk together the olive oil, lemon juice, salt, and crumbled oregano. Pour this over the potatoes, and stir well to ensure the potatoes are fully coated with the dressing.
Place the potatoes in a greased, ovenproof dish, sprinkle a little salt over them, and add a small amount of water to the bottom.
Roast the potatoes on the lowest shelf of the oven until they are golden brown and soft.
