Place the 1 large head broccoli florets into a large bowl and spray with Avocado or olive oil cooking spray. While spraying, turn the florets on all sides to evenly coat. Sprinkle with the 2 teaspoons garlic salt and 1/2 teaspoon ground black 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.
