Ideas for lentils?

[pennyplainknits]

I bought a bag of lentils- just the ordinary red split lentils, not puy lentils- a few months ago thinking I might need to make a veggie Shepard's pie for a house guest. I didn't, and now I have a bag of lentils sitting in my pantry I have no idea what to do with.

I've only ever had them as part of a stew before now. Any ideas? I can't eat tomato or cheese
