Final answer:
The standard method for cutting a quesadilla involves slicing it into wedges with a knife or pizza cutter after cooking.
Step-by-step explanation:
The procedure for cutting a quesadilla typically involves slicing it into wedges after it has been cooked. This is usually done either by using a knife or a pizza cutter. The most common way to cut a quesadilla is to place it on a cutting board and cut from the center to the edges, creating triangle-shaped pieces that are easy to handle and eat.
The specific method you've described, involving cutting a straight slit in aluminum foil with a utility knife and straight edge, seems to be part of a different procedure and not standard for cutting a quesadilla once it’s been prepared and cooked.
It's possible this method could be used as a technique to create an opening in the foil before cooking for steam to escape, or to partition the quesadilla, but this is not a typical or recommended method for slicing a quesadilla.
