Two bites into my sandwich and either:
1. Most of the contents have fallen out and I now need to eat it with a fork.
2. The roll/bread has come apart completely and I now need to eat it with a fork.
You need to use sandwich toothpicks, the tall ones you get in burgers at restaurants.
Your bread to meat layering is off, its not evenly stacked. You need to compensate for your poor sandwich building with these picks while eating, and potentially cut it in half/into thirds at the max only if it's really big.
You can grab em on Amazon for like 10 bucks for a 100. You should do that.
