I teach a class of (semi-)advcanced ESL learners (around high school level of English). Need help finding material to use

Not sure why I got hired for this job (very grateful) but I'm having trouble finding pieces of English writing that's not too dense and too easy and I can go over in two 1.5 hours per week. How do you all find material? I can talk about anything (politics and the such is okay for instance, fiction/non-fiction, etc.) but it needs to be an appropriate level while not being too long.

thanks in advance
