Spread the broccoli out in an even layer, & lightly coat with olive oil. *
Sprinkle salt, pepper, & garlic powder over top.
Bake for 15-20 minutes or until the edges begin to brown & the broccoli is tender-crisp.
Notes
*I used a "Misto" brand sprayer that you fill with your own oil. If you don't have one, you could toss the broccoli in a large bowl or drizzle the oil over top~ you don't need much, just enough to coat.
