In cast iron skillet large enough to hold apples in single layer, toast sunflower seeds until golden (about 3 to 5 minutes). Remove toasted seeds to mug or bowl.
. Core apples and place in cast iron skillet or camping pot, cutting off a side or two of some, if necessary, to make them fit in a single layer. Sprinkle cranberries, cinnamon, and toasted sunflower seeds into and around hollowed-out apples. Stuff star anise petals between apples and pour 1/4 cup water over top.
Cover and place skillet on grill grate over a medium flame for 10 minutes, until apples have released a lot of their juices, then remove cover and cook for 5 to 10 minutes longer, until juices have reduced and thickened slightly.
Let cool for 5 minutes, sprinkle with more cinnamon, and serve.
