The recipe is hers and its easy to follow; while it does take a little (lot) of prep work and time to cook it was well worth it. I had never heard of Pasitsio (Greek Lasagna) and at first when I thought I'd never make it again because it was not a quick dinner... however after tasting it I changed my mind.
I was a little afraid when I read it had a Bechamel sauce as I did not know what this was... turns out it's white sauce... something I've been making long before I ever turned 16. It was the first sauce I learned to make at my daddy's side in the kitchen.
Rather than post the recipe, I've provided the link... please follow it and try this dish, I promise you it's wonderful!
