leek, lemon and feta quiche!

A friend just sent me this recipe and I thought I'd share it because it seems amazing, easy to make and was described as 'light and cheerful'
I don't know about the calories but it looks okay to me, and it seems pretty adaptable if you want to change the half and half for milk and maybe take out the egg yolks and the liquor.
I think I might make it tonight!!
Enjoy
