Autumn Salad with Horseradish Vinaigrette

(recipe from Sprouted Kitchen)

3/4 lb. Brussels sprouts
3/4 lb. cauliflower florets
3 cups butternut squash, cut into 1/2"cubes
2 Tbsp. olive oil
1 Tbsp. white balsamic (I used regular balsamic vinegar)
3/4-1 tsp. sea salt
1 tsp. freshly ground pepper
few pinches of cayenne
1 cup cooked white beans, rinsed and drained
1/2 cup pomegranate seeds
2 packed cups arugula
1 Tbsp. prepared horseradish
1 large clove garlic
1/2 a shallot
1 tsp. honey
2 Tbsp. white wine vinegar
1/4 cup olive oil
1/2 tsp. each salt and pepper, to taste
handful of fresh chives and/or parsley
dollop of crème fraiche, optional

Preheat the oven to 400F.  Cut the Brussels in half lengthwise, and cut the cauliflower into similar size chunks.  Add both of these and the squash to a large rimmed baking tray.  Drizzle the vegetables with the olive oil, balsamic, salt, pepper, nutmeg, and a few pinches of cayenne and toss everything together with your hands to coat.  Roast in the upper third of the oven for 35 minutes, until edges are browned.

While the vegetables roast, make your dressing.  In a mini blender or processor, combine the horseradish, garlic, shallot, honey, white wine vinegar, olive oil, salt and pepper, herbs and crème fraiche, if using.  Blend everything together to mix well.  Taste for salt and pepper and set aside.

As soon as the hot tray is out of the oven, add the beans onto the tray and toss everything together.  Allow the vegetables to cool to room temperature.  Add the pomegranate seeds, arugula, and a good drizzle of the dressing and toss everything to coat.  Serve at room temperature.
