Preheat oven to 400 degrees. Place the potatoes in a 13"x9" baking dish and pour the olive oil over them. Add the garlic, dried oregano, salt and pepper to taste and toss well to coat with the oil. Arrange the wedges in a single layer.
Bake the potatoes for 15 minutes. Add the stock, then toss and bake for 10 minutes more. Add the lemon juice, toss and bake for 10 to 15 minutes more, or until the potatoes are cooked through.
If you like, preheat the broiler and broil the potatoes for 2 to 3 minutes, or until golden brown. Sprinkle with the fresh oregano and serve at once.
Notes
You can make this side dish vegetarian friendly by substituting vegetable stock for the chicken stock.
