Toast the nuts in a saute pan over medium heat with 1 tablespoon butter and 1 teaspoon salt. When the nuts start to take on a light golden color, add the rosemary and bloom for 1 more minute. Add the honey to the pan and remove from the heat.
To roast the Brussels sprouts:
Preheat the oven to 450 degrees F. Toss the Brussels sprouts with the canola oil, 1 teaspoon salt and pinch freshly ground black pepper. Lay out onto a sheet tray and roast for 10 to 12 minutes until they take color, but retain some texture. Remove from oven and set aside.
To finish the dish:
Saute the Granny Smith apple pieces in 1 tablespoon butter until they just take on color, about 2 minutes. Add the candied walnuts and roasted Brussels sprouts. Toss, and then add the juice of 1 lemon and adjust the seasoning as necessary.
