Note
If Manchego cheese is unavailable, you can substitute with Grana Padano or Parmigiano Reggiano.
If you need to prepare this a few hours ahead for a BBQ or dinner, you can make everything in advance. Simply place the Brussels sprouts, walnuts, and cheese on top of the dressing, and toss them together just before serving.
