(*Remember to first thaw pastry per package instructions. This can take up to 2 hours out of the freezer.)
Preheat oven to 400F. Then in a small bowl, combine brown sugar, cinnamon, and salt, and mix thoroughly then sprinkle 2 or 3 Tablespoons of the mix evenly on the puff pastry sheet.
Spread the apple slices on the puff pastry like so...
Then sprinkle with another Tablespoon of the brown sugar mixture, divide the butter into little dabs and place them on the apples as shown, and grate the cheese over the top of the tart.
Bake for 20 to 22 minutes on center rack and that's it! We enjoyed ours with a scoop of vanilla bean ice cream.
