Why is sandwich meat circular when the bread is square?

It goes half way to help if you have a round of sandwiches

On a practical level, most tins are circular in section. (OK, corned beef and sardines aren't.) It's probably cheaper to make them round. If you buy your sandwich meat from a deli, you'll find you can buy it square. But then again, some bread is square and some is oblong..... They keep trying to market square eggs, but don't seem to be getting anywhere. Porbebly animal cruelty people objecting...

Most lunch meats are formed in tubes,bread is made in pans?

Porbebly should porblobby read probably....

You can hard boil a round egg square if you're careful.

I'm with deja. Different ways of making them make different shapes. Then there are places where they slice the meat for you, and it's just irregular instead of any specific shape.

Kaiser rolls are round.
