Lightly brush tortilla with olive oil on both sides. Toast on a hot frying pan on each side for 30 seconds.

Lay tortilla on a cookie sheet lined with parchment paper. Spread hazelnut spread to cover the tortilla, leaving a slight border. Evenly distribute marshmallows across the tortilla. Bake at 400°F for 8-12 minutes until marshmallows are slightly melted and golden brown. Sprinkle the top of the pizza with graham crackers.

Cut into wedges or strips and serve warm.

Warning: This will be messy but delicious!
