We use this Delia recipe!
https://www.deliaonline.com/recipes...vegetarian-moussaka-with-ricotta-topping.html
ally has more of a veggie compote, as the topping is too dairyfied for her...although I have tried it with different milks for me, too, and it was good with oat.
I also use stock instead of red wine when the girls are having it, but have to say it is yummiest with wine!
