Cut the broccoli into florets. Place broccoli on prepared pan. Pour the olive oil on the broccoli. Sprinkle with garlic salt, pepper and Parmesan cheese. Mix until everything is coated. Put in the oven in the top rack for 8-12 minutes.
NOTE: The cheese has to melt and the broccoli gets a bright green color. If you like, keep it in the oven for few extra minutes until starts getting light brown and the broccoli will get crunchy.
