Bring a pot of water to a boil, salt the water and cook the farro to tender, 20 minutes or so.
Meanwhile, toss the mushrooms with about 1/4 cup EVOO or just enough to lightly coat, and then season with the thyme. Roast to deeply fragrant and brown. Season with salt and pepper.
While the mushrooms are in the oven, heat about 2 tablespoons EVOO, 2 turns of the pan, in a skillet over medium-high heat. Add the garlic, shallots and asparagus and cook to tender crisp, 2 to 3 minutes. Add the kale and wilt, season with salt and pepper and nutmeg to taste. Deglaze with the sherry.
Toast the nuts in a small skillet until browned and fragrant.
Drain the faro and combine with the vegetables. Cool and store for a make-ahead meal. The farro can be served room temp or reheated in a microwave or skillet. Store the toasted nuts in an airtight container at room temp. Reheat the mushrooms in a skillet to warm through. Serve the farro and vegetables sprinkled with the nuts, a little lemon juice and top with roasted mushrooms.
Alternatively, the farro can be served as a cold salad and the mushrooms can be roasted off the night you want to serve it. If the cold farro is too dry, dress with sherry vinegar or lemon juice, and more EVOO.
