The first one was this Macarona bil Béchamel, or Macaroni with Bechamel Sauce and Mushroom Filling, which you can find in the amazing Alf Hana blog. (Thank you, ladies, this blog is incredible and a great source of info for lovers of Egyptian cuisine who are also vegan.)
My attempt was quite successful. Take a look:
Bechamel sauce is supposed to be quite greasy, but I'd still like to experiment a bit more to get it lighter. And next time I make it I am going to add lentils to the mushroom mix, so this can be a complete meal.
