What does 耳 stand for in these sentences?

“ パン耳どしてますか” From what I know this means “do you have any bread?” I wanted to
use it in another way, just to see if it would form a similar sentence
translation, so I changed “pan” to “gohan” (ごはん耳どしてますか), but instead I got a
translation of “Do you listen?” I want to know what mimi/耳 stands for in this
context.

I’m aware not all character positions are interchangeable, just curious about
the characters (耳) meaning in a sentence. Thanks!

Update: Thank you Foogod for the answer! I didn’t process that “bread ear”
could refer to the crusts. Thank you l'électeur for the updated explanation,
it definitely helps a lot!

meaning
What does 耳 mean in these contexts?
[パン耳](https://jisho.org/search/%E3%83%91%E3%83%B3%E8%80%B3) ("bread ear") is
actually an expression that means "bread crust" in Japanese, so this actually
means "Do you have any bread crusts?"

This is why you can't replace パン with other words, because this is a special
meaning for 耳 that only works when combined with パン.

> 「パン耳どしてますか」

does **not** mean:

> “Do you have any bread?”

That is not even close if I may be completely honest.

「耳{みみ}」, in this context, means " **edges** " or " **crust** ". We say
「パンの耳」、「ピザの耳」、「紙{かみ}の耳」, etc. (紙 means "paper".)

「ごはん（の）耳」 makes little to no sense as rice has no edges.

「 **ど** してますか」 is a very informal way of saying 「 **どう** してますか」, which means "
**What do you do with ~~?** ". So, 「パン耳どしてますか」 means " **What do you (usually)
do with bread crust?** "

In other words, it is asking "Do you use/eat the bread crust in any way or do
you just throw it away?"

Thus, 「ごはん耳どしてますか」 makes no sense and it certainly does not mean “Do you
listen?”. Wonder who told you that.
