And you won’t believe just how simple it is to make.
The classic combination of Fontina cheese, mushrooms, and fresh thyme make thiscasserolefeel so light.
Since the broccoli doesn’t get overcooked in the first place, the leftovers are particularly great.
A nice glass of red wine is appropriate, too.
