What is the total cook time for a Grilled Cheese sandwich?

The total cook time for a Grilled Cheese sandwich is indeed 1:30, which is the correct answer. This time allows for optimal cooking, ensuring that the bread is toasted to a golden brown while the cheese melts thoroughly. It's crucial for achieving that perfect balance of texture and flavor, where the outside is crispy and the inside is gooey.

The other times provided would either not allow enough cooking time for the cheese to melt properly, resulting in a sandwich that might be undercooked or barely toasted, or they might overcook the sandwich, making it too crunchy or risking burning the bread. The 1:30 cook time is specifically calibrated to deliver the best quality sandwich for guests, maintaining Zaxby's standards for freshness and taste.
