To prepare the sunflower seeds, warm a small non-stick skillet over medium heat and add the sunflower seeds. Let the sunflower seeds warm up a bit, then pour in the maple syrup, a pinch of salt and a tiny dash of cayenne pepper, if desired. Toast the seeds while stirring constantly until most of the maple syrup has evaporated and the sunflower seeds are turning lightly golden on the edges, about 3 to 5 minutes. Transfer the seeds to a plate to cool.
