In the meantime, preheat oven to 350°F and spread the broccoli onto a baking sheet. Spray lightly with olive oil spray and salt and pepper generously. Place the pan in the oven and cook for five minutes. Using a spatula, flip the broccoli lightly. Return to oven and cook for an additional 5 minutes. Add the broccoli to the sauce and uncover. Cook for 5-8 minutes, to thicken a bit. Stir frequently.
