If your farro and lentils are not cooked, go ahead and cook and cool them (check PDF or Meal Prep Guide for instructions). Or skip them all together for a lighter side salad.
Preheat the oven to 450F or 425F convection. Line a baking sheet with parchment paper. Add carrots, olive oil and salt and toss to coat. Bake for 20-30 minutes, or until bottoms are caramelized and slightly charred in spots (do not stir). Remove from the oven and let cool while you make the dressing and assemble the salad.
In a jar with a lid, add all of the dressing ingredients. Shake vigorously to combine.
In a large bowl, add the radicchio and toss with about ¼ cup of the dressing to coat. Transfer to your serving platter and sprinkle with salt. Add the lentils and farro to the bowl and toss with a bit more dressing (about 2 tablespoons). Scatter over top the radicchio and sprinkle with salt.
Add the warm carrots to the bowl and toss with a bit more dressing (about 1 tablespoon). Scatter over the lentils and farro and sprinkle with salt. Drizzle the salad with more dressing (you will have about ½ cup dressing leftover to save for future salads).
Finally, top with fresh parsley or scallions, toasted almonds, shaved parmesan, and one final sprinkle of salt and freshly ground black pepper.
