Sumac spiced Wedges

Since first trying sumac at my Lebanese friend, Sues place.
I have found the spice works well with many foods I create, so I use it often.
I cook my wegde potatoes in the oven on lined paper.

1kg potatoes cut into wedges
1 teaspoon sumac
1/4 teaspoon chili
S/p
1 egg white, lightly beaten


Mix egg white sumac, chilli and s/p
Cut potato into wedges add to sumac mix stir through till covered
Bake 200 degrees C in oven for 30-40 mins
