What is the final step in assembling a deluxe PJ?

The final step in assembling a deluxe PJ is adding the top of the bun. This step is crucial because it completes the sandwich and ensures all components are neatly contained. A sandwich is typically built from the bottom bun upwards, layering each component to create the desired flavor and texture. Once all other ingredients, such as the grilled filet, melted cheese, and fresh lettuce have been placed, topping it with the bun secures these elements and prepares the sandwich for serving. This step signifies that the assembly is complete and ready for delivery to customers. The inclusion of the top bun is essential in providing a traditional sandwich form and maintaining the integrity of its structure during handling and consumption.
