Grate the carrots and radishes coarsely. Wash and sort the radish leaves, and chop or julienne. Put them in a bowl. In a small bowl, whisk the lemon juice and cumin, cinnamon, and salt. Whisk in the olive oil gradually. Pour the dressing over the carrots and toss to mix. Just before serving, add the pumpkinseeds, peanuts, and feta cheese and toss.
