Preheat the oven to 400 degrees. Lay the broccoli out on a baking sheet and brush with olive oil. Season with garlic powder, salt, and pepper. Roast for 30-35 minutes or until fork tender, flipping halfway through or as any broccoli florets begin to burn.

While broccoli cooks, grate the Parmesan and set aside. Place the walnuts in a small skillet over medium-high heat and cook, shaking the pan often, until fragrant and lightly browned, about 5 minutes. Set aside.

Once broccoli is cooked, immediately transfer to a serving platter and garnish with Parmesan cheese, walnuts, and pomegranates.
