RSS format?

I’m running 2 installations of WordPress and I want to put the RSS feed from one WP blog in a sidebar on the other blog. I want it to be in the following format:

[Post title]
by [Author Name]
[# of comments]

Is there a plugin that will make this easy? I’m brand new to RSS… Do I need to change the output of the one RSS feed? Or do I need to change the way the other page interprets the RSS feed coming from the first page?

Forgive my general idiocy on the subject.
