Roasted Cauliflower

I've been meaning to make this forever... Recipe from a NAMI event from Shana:

Roasted Cauliflower
5 to 6 cups cauliflower florets, about 1 1/2 inches in diameter (from 1 medium cauliflower)
1/4 cup extra-virgin olive oil
1 tablespoon sliced garlic
2 tablespoons lemon juice
1 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons grated Parmesan (I usually omit this)
Chopped chives, for garnish (I always forget this)

Preheat the oven to 500 degrees F.

Place the cauliflower florets in a large saute pan or a roasting pan (I use a 9x13 glass pan). Drizzle the olive oil over the cauliflower, and season with the garlic, lemon juice, salt and pepper. Place the saute/roasting pan in the oven and cook for 15 minutes, stirring occasionally to ensure even roasting. Remove from the oven and sprinkle with chopped chives and serve immediately while still warm.
