Have been trying to find split buns here in Huntsville, AL, to no avail. I have checked every grocery stores bakery and bread aisle. We have bratwurst every week, and I absoltey cannot stand regular hot dog buns. I did find a bratwurst type roll at Target, but it wasn’t a split bun (top loading). There are lots of types of hogie rolls (split in half). I’ll keep looking and hopefully will find them soon.
If ya email me, I have a friend right now in Mass.. buying me some and sending them down.. I will get more and get them to you if you want.
