We started baking our own bread for subs several months ago using our pizza dough and I’ll never go back to buying hoagie buns again.
We take a 10 oz dough ball and roll it out in an oval shape, about 10"x5". Then roll it up tightly so it is 10" long. Cover and set it on a pizza pan to rise for about 15-20 minutes. Cut a slit along the length of the top of bun for split top, butter the top lightly and run through oven, we then let it cool and wrap in plastic wrap and they hold fine for a couple days.
