Preheat oven to 300 and line a baking sheet with foil. In a medium bowl, combine the nuts, garlic salt and cayenne. Add the margarine and thoroughly combine. Layer onto the lined baking sheet and bake for about a half an hour. Stir and flip over the nuts. I know, that’s not easy, but you’ll be able to tell which side is which since the cooked side will be dry-looking. Bake another 20-30 minutes. Let cool, then transfer to an air tight container if not eating right away. Enjoy!
