I followed the recipe exactly (well, I doubled it for leftovers) and the only thing I would change next time is adding more spinach. I really doubt the recipe makes only 2 servings. With the recipe doubled, I'd say there were easily 6 servings. Especially if you served it with a salad.
My 9-year-old went back twice to refill her bowl. Her favorite part was the cheese, but I would agree with the other reviewer that it isn't needed. But, if it makes it more appealing to the kids, it's worth it to keep it in the recipe.
The sausage is in there more for flavoring; it's way more lentil and a little sausage casserole.
I will be making this regularly.
