I'm all about cooking meals ahead and storing them in the freezer because I am super busy with work and can't be bothered to cook a fresh meal every day. I like to buy cheap Tupperware in bulk to store all of my meals to make it more cost efficient. I usually only keep meals in the freezer up to one month, otherwise they start to develop freezer burn. Some of the best Greek meals to cook ahead of time are moussaka, pastitsio, fava, lentils, kokkinisto, keftedes, and soutzoukakia!
