# Boil the macaroni at first, drain it, and let it stand to cool down.
# Prepare the sauce of the macaroni by whisking the mixture of
milk, vegetable oil and egg white while the macaroni cools down.
# Grease the oven tray as preparing tray borek. Superpose the first 3 yufkas onto the oven tray by putting mixture between them. Cut the edges which hang down of the edges of the tray and them lay them onto the tray also.
# After placing 3 yufkas onto the tray, place the cool macaroni and grated feta
cheese on the yufkas. Pour some of the mixture all over the macaroni.
# Place the remaining 3 yufkas onto the tray also by the same way.
# Place the smoothest yufka on the top. Mix 2 or 3 tbsp of mixture with yolk and spread it all over the yufka standing on the top.
# Slice the borek into squares at first, and then slice each square into 2 pieces to shape into triangles.
# Place it into cold oven. Bake it in 347 F until its surface turns to red (for about 45-50 minutes). Serve it warm.
