Help me identify this delicious thing

Hi everyone,

we visited Montenegro in 2018 and stayed in Dobrota. On the way to the old town of Kotor, there was a restaurant where we had this simple but delicious bread and cheese pastry for lunch. It had tomato, prosciutto, maybe rucola and other fillings and was absolutely delicious. I can’t remember the restaurant or the name, but here’s a picture: imgur

We are coming back to Montenegro and my question is: was this a random dish sold at a touristy restaurant, or some local delicacy? What might it be called, if I wanted to find one? I’ve looked at lists of traditional food but I’m starting to think this was just a random thing or something. 😀

Thanks and pardon my ignorance in advance. I promise I’ll eat other things there too. (Unless I find this one in which case I might eat like 37 to make up for lost time together)
