Butter makes the pastry flakier. When olive oil is used, it gives it a different texture. It maybe feels a little denser, and can make even store bought phyllo feel homemade. For me, it all depends on the situation. Sometimes I even do a half butter, half olive oil blend.
Definitely butter for sweets. Recipes for homemade filo are made with lots of butter. Had a cooking lesson on the weekend. My cousin was teaching me to make Kastellorizian sweet - Katoumathia. Katoumathia is fried flaky pastry garnished with sugar, water and cloves - flour, water kneaded and rolled out. cut into pieces. Each piece rolled out again and lots and lots (and lots more) melted butter spread over, rolled into strands, squished and rolled out again and fried in butter. Unfortunately this cannot be made with filo. BUT, I have made similar with frozen roti and lots and lots of butter garnished with sugar, water and cloves.
Fresh Greek chamomile can be great for falling asleep and relaxing! Greek herbs have been used for hundreds of years for medicinal and lifestyle purposes. There is so much you can use that comes from the earth.
I love grilled octopus. I like to make it with the whole head, and I know that some people don't like to prepare it that way, but I don't like to waste food. I make my octopus using a super simple marinade, just olive oil, lemon, sea salt, oregano, pepper and vinegar.
