Arrange orange slices and beet wedges alongside yogurt. Drizzle salad with more olive oil and sprinkle with salt to taste. Garnish with pumpkin seeds and mint leaves.
Remove from the oven and let cool enough to handle. Peel the beets and discard the skin. Slice into ¼-inch thick slices. To serve the Salad: Arrange the beet slices down on your serving plate.
I had this at a friend's house a few weeks ago. The original recipe came from Cuisine magazine and used baby spinach instead of silverbeet. I am always trying to find ways to include silverbeet.
