Looks delicious! We have a dish very similar to this called sarma (stuffed cabbage), and I love it!

We also have that too called lahana sarma in Turkey too. Love it too (hard to make tho) 
Interesting. The two dishes look similar, what is the difference between the two (lahana sarma & Zucchini filling)?
Yes, sarma is hard to make so we often make it more like a casserole, or as we say in the Midwest, hotdish. 😁
