To make ahead
Store loosely covered with plastic wrap at room temperature for up to 3 days.
This means they wont spike your blood sugar like other fruits might.
With that said, you could use gluten-free puff pastry to make an equally delicious gluten-free apple turnover.

you could also use othervarieties of applesthat are sweeter, like Honeycrisp or Gala.
No, it’s possible for you to keep the peels on the apples.
They will give the turnovers more texture, plus you’ll save time on prep.
