In times of food shortage or restriction, we often turn to simple, inexpensive and nutritious recipes. Greek Halva is a perfect example: it's a flourless, egg-free, dairy-free, no-bake dessert - a surprisingly tasty preparation made in a saucepan. I remember very well the first time I tried it: it was made for us by a Greek family friend when I was a teenager. I loved it so much that I immediately asked her for the recipe. Since then, I've always pulled it out whenever I'm in the mood for a simple, comforting sweet that's full of memories. Halva is found in many countries (India, Turkey, Lebanon, Persia...), but this Greek version is particularly easy to make. The texture is reminiscent of fudge or compact marzipan. Cut into small slices as you would a piece of chocolate.
