Chocolate Marshmallow Filo Fingers

4 sheets filo dough, thawed according to the package directions
Cooking spray, preferably butter flavored
Semi-sweet chocolate chips, about 1/2 cup (max)
Mini marshmallows, about 1 cup
Granulated sugar or colored sugar sprinkles 

Preheat the oven to 350 degrees. Line a baking sheet with parchment paper.
Unroll 1 sheet of filo on a flat surface (keep the other sheets covered so they don't dry out). Spray the sheet with cooking spray. Fold in half lengthwise, and spray the top. Use a sharp knife or pizza cutter to cut out 4 equal rectangles. 
Line up the chocolate chips and marshmallows on one end of the rectangles. Here's what it will look like:
