What can you make with grape leaves besides dolmas?

I love the taste of stuffed grape leaves/ dolmas – but in particular I really love the leaves more than the rice. I’m wondering if there is anything else tasty to make with the leaves – can you sautee them like spinach or kale? I found a few recipes online for casseroles but am wondering if anyone here has ever actually tried grape leaves in anything but a dolma recipe. Do they have good nutritional value like other green leafy vegetables do? Thanks!
