First prepare the orange segments. Slice a thin layer off the top and bottom of the orange, then place the orange right side up on the cutting board and simply slice the peel downward, using a chef’s knife and following the natural curve of the orange. A little of the white part (called the “pith”) is okay, just try to get as much orange as you can. Then slice the orange widthwise and cut each piece into 3/4 inch segments.
Then toast the sesame seeds. Preheat a small, heavy bottomed pan over low/medium heat. Add the sesame seeds and stir often for about 2 minutes. They should be toasting up by then (if not, then raise the heat). Use a spatula to toss continuously for another minute or so, until they are varying shades of toasty brown. Remove from pan ASAP to prevent burning.
Pour the dressing into a large mixing bowl. Add wild rice, currants and lettuce. Using tongs, toss to coat. Add oranges and sesame seeds, and toss again. Lastly, fold in the beets. Serve.
