Pre-heat the oven to 425°F.
Place the EVOO (eyeball it), garlic, chili powder and grill seasoning in the bottom of a large bowl and add the broccoli spears. Toss to coat the broccoli evenly.
Transfer the broccoli to a large nonstick baking sheet. Roast the broccoli until the ends are crisp and brown and the stalks are tender, 17-20 minutes.
