To make the Pumpkin Quesadillas take two of the flour tortillas and use a small, sharp knife to cut out Jack-o-Lantern faces on each of them.
Place half a tablespoon of butter in a medium skillet and heat until melted. Add the jack-o-lantern face tortilla, face down, on the butter in the skillet.
Cook for 2-3 minutes or until heated and starting to brown. Remove from pan.
Place another half tablespoon of butter in the pan and allow it to melt.
Place a regular tortilla in the pan, sprinkle with half the cheese, then top with 4 half slices of American cheese. Put the jack-o-lantern face tortilla (face side up) on top of the cheese.
Cook for 2 minutes then cover with a lid and cook for 1 minute or until the cheese has melted. Remove from pan.
Repeat with the other quesadilla. If desired put a piece of green pepper at the top before serving to make a pumpkin stem.
