Ok, this is an oldie but a goody. My mom would do these after my dad was done charring the burgers!
1 banana per person. I like a somewhat firm but not green banana.
Cut the banana lengthwise, but not all the way through, making a pocket. Now crush graham crackers and put in pocket, but don't fill. Now add chocolate chips to top of pocket.
Heat Pellet grill to 300 and put bananas on for 1 hour or until soft. I usually use a chunk of aluminum foil to make a base for the bananas so they sit upright.
They will be very hot and floppy, so be careful when you remove. Plate next to a big scoop of ice cream and finish by topping with more crushed graham crackers.
