Place the honey in a microwave safe bowl and warm the honey in the microwave for 20 seconds. Preheat the oven to 350 degrees.
Add the honey, oil, salt and cayenne to a bowl and mix well. Add the sunflower seeds and stir to coat.
Place the honey-coated sunflower seeds on a baking tray lined with parchment and roast for 20 minutes.
Remove the seeds from the oven and allow to cool completely.
Check the sunflower seeds often when roasting to ensure they don't burn! Give them a good stir halfway through to ensure even cooking.
