Tuna Pie looks nice and it's delicious and healthy recipe.
Turkish yoghurt is a very firm and creamy yoghurt - if you open a can you can turn it upside down and nothing will fall out (hopefully). Find a similar product and give it a go! But don't try it with a runny yoghurt, that won't turn out well. The kind I use has a fat content of 10%, so I think it would be good if you can find something that's not too fatty.
