As it was coooking, the casserole smelled out of this world. But, the potatoes were flavorless and the filling was kind of mushy but flavorful. If I make this again, I will make my mashed potatoes with some margarine and green onions and I'll let the dish stand longer after cooking to firm-up.
YUM! This is one of the heartiest vegetarian recipes I've ever made! I converted the measurements to American units and adjusted the amounts. See my blog post for details: http://veganomics101.wordpress.com/2012/02/04/mushroom-shepherds-pie/
I also added margarine and soy milk to the potatoes and soy sauce to the filling.
Thank you for posting this; I loved loved loved it!
