Which step comes last when assembling a spicy AM sandwich?

The last step in assembling a spicy AM sandwich is to top it with the buttered, toasted bun. This step concludes the assembly process, ensuring that all other components—the filet, cheese, and pickles—are properly arranged before sealing the sandwich.

This sequence enhances the final presentation and prevents any ingredients from falling out or misaligning. The toasted bun also keeps the sandwich warm and adds a pleasing texture. Each prior step builds upon the last, contributing to a well-structured sandwich, but placing the toasted bun on top finalizes the assembly.
