Cut off the tops and bottoms of the zucchinis. Slice a thin layer to reveal the flesh. Use a vegetable corer or teaspoon to scoop out the flesh, creating a zucchini boat ½ cm (¼ inch) thick. Mix olive oil and oregano in a small bowl, and brush the mixture all over the insides of the zucchini. Lightly season with salt and pepper. Arrange zucchini in a small baking dish or non-stick pan and bake for 12-15 minutes, until slightly softened.
