Thank you :) We have something similar, we call it "Airan", it's generally a mixture of yogurt and water, some love to add salt but I don't.

Another very famous Bulgarian cold soup, called "Tarator", based on yogurt, water, cucumbers, some dill, salt and garlic to spice it up, a pinch of grated walnuts. It is excellent for the summer heat :)

Sounds similar to some greek dishes ive seen. Thanks for the replies!

I guess you mean the Greek Tzatziki salad? Almost the same ingredients, apart from the water. The Bulgarian version is called Snow-White (Snezhanka/Снежанка) :)
I think the only difference between Tsatsiki and Snow-White is that we use sunflower oil instead of olive oil.
