What is a key step in assembling a deluxe PJ?

Placing the filet rough side down is a crucial step in assembling a deluxe PJ because it ensures that the texture and flavor of the chicken filet are optimized when served. The rough side of the filet has a greater surface area, which allows it to better hold onto seasonings, sauces, and any toppings, leading to a more flavorful bite. Additionally, placing it rough side down can enhance the overall presentation of the sandwich, as the smoother side will be facing outward.

When considering other factors in assembling the sandwich, such as condiments and toppings, ensuring that the filet is prepared correctly forms the foundation of a delicious and visually appealing deluxe PJ. This approach also aligns with maintaining the quality standards that Chick-fil-A upholds for its food.
