One of my favorite things to do in Istanbul while wandering the streets hungry, is finding someone selling Doner Kebabs and buying one. :) Doner Kebabs use meat (like below) and they stuff it into a flatbread or wrap with lettuce, tomato, onion, etc. It's delicious.
The great thing is that it's relatively cheap! So you can get a filling meal that tastes delicious at a good price. What else could you ask for?! :)
On another note, my weekly portrait is coming up soon. It was supposed to come sooner, but I had some bumps in my plans that I think have smoothed themselves out now. :) So be on the lookout!
