What to do with fermented lentils? 3 days ago, I decided to do some brown lentils, so I did a lentil soup with zucchinis and spice (a lot of cumin and cayenne). I didn't have tupperware so I left  it in the pot with the lid.

And this morning, I found out they are fermenting. then is some bubbles and a strong fermenting smell, still a "clean" smell.

I'm not sure what to do, part of me want to throw it away but I don't want to waste it either. Can I save it or maybe use it for something else?

thanks
Throw it away, it's spoiled and probably contains several colonies of foodborne illnesses. Sealing food isn't sufficient to stop it going off, you need to refrigerate it or freeze it.
