Toss fruit. Sprinkle the sugar over the fruit and then squeeze the lemon over the fruit (make sure to remove the seeds!). Toss the fruit until well coated.
Prepare tortillas. Brush the melted butter over the tortillas making sure to turn them to butter both sides. Use a pizza cutter or sharp knife to cut the tortillas into chip-sized wedges.
Prepare sugar mixture. In a small bowl combine the sugar and cinnamon together. Place the tortillas in a gallon bag or large sealable container. Add the cinnamon sugar, seal the bag and shake until the chips are covered in cinnamon sugar.
