How do I send someone an entire email distribution list on gmail?

I’ve tried to Google this.

Here’s an example:

I created a group called Zumba in gmail that has 50 email addresses in it. The person taking over the Zumba class needs my entire mailing list, so I’m hoping there is some way to send her the group with a few clicks and she can put the whole group in her contacts with a few clicks.

I don’t use Outlook, it’s in regular gmail.
