Preheat oven to 400F.
Mix together the oil, garlic, red pepper flakes, salt and pepper. Toss together the broccoli and the oil mixture in a large bowl. You may have to adjust the oil a bit if your bunch of broccoli is smallish. You don't want it swimming in oil on the cookies sheet. Put broccoli on cookie sheet. Place in the oven for about 10-15 minutes. Be sure and check often to make sure it's not burning, you want it to caramalize but not burn. If you don't like al dente brocoli, cook a little longer. I usually remove after 10-15 minutes. When the broccoli is as done as you like remove from the oven and toss with the cheese, serve and enjoy.
