what should Liz do with a bag of lentils?

So hey, question for you all!

Today I acquired the bag of red lentils pictured above -- look when outgoing tenants leave stuff in their apartments at the end of their leases, sometimes we make off with various items before either donating the rest to the local re-use center or chucking it in the trash (depending on the nature and condition of said items), and dry goods are dead useful, generally speaking -- but unfortunately I have precisely zero idea what to do with them, aside from, you know, maybe make lentil soup with mixed vegetables.

Therefore: what are some good but fairly low-effort lentil-based recipes?
