Kousa Bi Gebna (Zucchini with Cheese)

This is meant as a side dish, but I served a whole recipe as a main vegetarian dish. As a main, it would serve four (the two of us will have two dinner); as a side, it would serve 6-8. I used gruyère for the cheese. Although it's very simple, it was very tasty. In my edition, the recipe didn't say what to do with the sautéed onions, so I searched a bit online and found almost exactly the same recipe that said stir together the zuke and the onions before putting into the casserole. It also said to add paprika, so I added a goodly dash of smoked paprika. Easy and tasty.
