Please advise on my situation.

I have something like this


A Yaml file that contains


Application:
 - App1
 - App2


When I puts that yaml file for that application field, I get App1,App2.
How can I add quotes to each application.  I'd like my output to be
"App1,App2" which includes the quotes in the output

I was thinking maybe through the use of gsub but I'm still new to ruby.
Could someone provide some aid?
