you should start a reading circle.
the easiest is to meet up together and take turns reading aloud, discussing as you go. reading is a skill, and you'll all get better as you go.
as to what to read, there are many classic intro texts, but something you personally found instructive or insightful or applicable to your situation will probably be particularly meaningful for your friends. you can let questions that arise from there guide your next picks.
if you're meeting for an hour, something that's 15 minutes long is probably the right length to get started.
