Dry-roasting: Add the oats and sunflower seeds to a cast-iron skillet or non-stick pan. Stir over medium heat until golden. It will take 5-7 minutes in a cast-iron skillet and about 3 minutes in a non-stick pan.
Make the granola: Remove the skillet from the heat. Add in the coconut and maple syrup. Stir until everything is evenly coated. Add in a pinch of salt and the vanilla extract. Stir again.
Let it crisp up: Let the granola cool for about 10 minutes. To speed up the process, you can remove it from the hot pan and transfer it to a baking sheet. Serve right away or transfer it to an airtight container.
