Orange Salad with Parmesan and Almonds

1. Supreme the oranges. (You can google a video demo of how to do that.)
2. Save the leftover orange carcasses and squeeze their juices into a bowl.
3. In a separate bowl, toss the arugula with the olive oil and a tablespoon of the reserved orange juice.
4. Put the dressed arugula on a platter. Arrange the orange segments, Parmesan shavings and almonds over the arugula. Drizzle on a little extra orange juice if you like.
4. Sprinkle a pinch of coarse sea salt over the salad and a grind of fresh black pepper.
