Preheat an oiled skillet, or grill over medium heat.
Spread about 2 tablespoons of peanut butter over one side of each tortilla. Arrange a few slices of banana and raspberries on top of the peanut butter and fold each quesadilla in half.
Place each quesadilla into the skillet, one at a time and check each quesadilla after just a minute or two, or as soon as it starts to turn golden. Flip and cook the other side for an additional minute or two!
Serve warm & Enjoy!
