Slow Cooker Vegetarian Lentil Stew

I've been hunting for a recipe similar to a dish I had at a friend's years ago. I found this Knorr one and although I can't even recall what my friend's tasted like now, I think this came out pretty tasty. The boyfriend put it together as I had to dash off to work unexpectedly. He thought maybe adding some corn would be nice another time.
