Heat the milk and the margarine so that it melts (it should be tepid). Add it to the bowl where you will knead. Add the sugar, the yeast and the egg white... mix slightly.
Add the flour and finally the salt. Mix - knead a little (by hand, you don't need a mixer) and set it aside to rise for half an hour.
Mix the cheeses and crumble them using a fork.
Roll out 2 oblong filo sheets (one at a time). Brush them lightly with butter and spread the cheese mix.
Fold into three parts like an envelope (retaining the oblong shape).
Set it in front of you horizontally and cut it vertically into 10 parts. Each part once more at the middle (again, vertically) but not from the top but a little further down. Like a pair of pants...
Twist each "leg" into a rose...
Wait for about 10 minutes, brush with egg (the egg yolk with a little milk) and bake for about half an hour at 170°C.
