Preheat grill (to medium heat). Cut a 12 x 18-inch sheet of nonstick foil.
Place apple slices on foil along with butter, brown sugar and cinnamon and dried cranberries.
Wrap packet securely with double-fold seals, allowing for a bit of room for heat expansion.
Place packet on grill; cover and cook for about 15 minutes over medium heat.
Be careful when removing from the grill it will be very hot! Also, use caution when opening packets because there will be hot steam as you open them.
We serve right in the packets. There will be juices on the bottom of the packet so gently stir the apples before taking a bite.
This would be fun to set up as a baked apple bar. Set all the ingredients out for your guests and let them top with whatever they like. This is delicious put into a bowl and a little ice cream served on top! I will take the extra juices from the foil packet and drizzle it over the ice cream.
