  5. Place oven rack on uppermost position. Set oven to broil.

  6. To make stuffing, add vegetables, parsley, thyme, and Parmigiano-Reggiano to barley. Stir to combine.

  7. Make sure mushrooms are hollow-side up. Scoop about 1 cup of stuffing into each cap. Top with provolone slices and extra Parmigiano-Reggiano. Transfer to oven and broil for 5 minutes, or until cheese melts.
