Preheat oven to 425 and grease a baking stone or baking sheet. You can use a spray or drizzle some olive oil on the sheet.  

Cut broccoli into bite size pieces and place in a mixing bowl. Drizzle with oil and mix well. Add garlic and mix well. Season with salt and pepper.  

Spread onto prepared baking sheet and bake for 20 minutes or until broccoli is tender.
