Blistered Broccoli

1 head broccoli, cut into small florets

1/2 teaspoon red pepper flakes

In a bowl, toss broccoli florets with oil and season with salt and pepper. Carefully remove pan from oven and pour broccoli in, spreading into an even layer. Drizzle lightly with oil and return pan to oven.
