What's the best way to toast the hoagie roll?
Butter the cut sides and toast in a skillet over medium heat until golden, about 2–3 minutes. This prevents sogginess from au jus.

Substitute Thousand Island or a mix of mayo, ketchup, and relish for similar tangy-creamy flavor.
How do I prevent the sandwich from falling apart?
Keep the au jus warm (not boiling), toast the roll thoroughly, and don't over-stuff—the melted cheese acts as a binder.
