Place the broccoli florets into a large bowl and spray with olive oil spray. While spraying, turn the florets on all sides to evenly coat. Sprinkle with the garlic salt and pepper, and thoroughly stir to coat.
Cook the broccoli in the air fryer, in 2 batches, for 6-8 minutes (depending on the size of your florets). Shake the basket halfway.
Notes
if you don't like broccoli, you may use cauliflower. Cook time will VARY.
