Interesting note about the importance of the olive oil, which is mentioned in both the Greek and Turkish, but not the Lebanese recipe.
ETA not THIS Lebanese recipe, which uses 2Tb veg oil
"Called loobyeh (pronounced LOO-beh), this comforting vegetable stew is a staple in Lebanon. "
OTOH, I found this one
Saveur
…which talks about olive oil as well.
“Greek Style Green Beans-Fasolakia Lathera…where vegetables are cooked in olive oil and tomato along with herbs.”
“Ottoman-era dishes called zeytinagli, in which vegetables are cooked for a long time in olive oil,”
