Oh come on! Get real. She makes a sandwich. He makes a sandwich. Who cares which sex makes a sandwich. Are women not allowed to make sandwiches anymore? Come on. (All I know is that I'm hungry and I would really appreciate a sandwich right now, and I don't care which sex makes it.)
You are right. The ending of the word alone says that it is a little bread .
Roll is actually the best answer and sandwich is wrong. I reported it as a problem and included this links:
This is a panino https://it.wikipedia.org/wiki/Panino
and this is a panino imbottito https://it.wikipedia.org/wiki/Panino_imbottito
and this is a sandwich https://it.wikipedia.org/wiki/Sandwich
I think this is similar to faire in French if I'm not the only one here whose into that romance language as well. It is like "do" in English.
