I think a large part of English culture is cooking traditional family meals, like this, that are guaranteed to fill everybody up. And they're always meaty. Which poses an issue for those of us who have decided to cut out their intake completely, or (like me) think it's important to at least reduce our consumption, but really don't want to miss out on the hearty dishes we've always eaten.
Over the last two years I've stocked up on several vegetarian cook books to inspire this new venture, including The Hairy Bikers Go Veggie, which is a brilliant book because it's definitely written for meat eaters transitioning. (Well, it's marketed as a diet book so I just ignore the low fat commentary). My favourite chapter is the "we miss meat" bit, because they make a point to cook really hearty, traditional recipes, reinvented. And this shepherds pie is based on their Mushroom and Lentil Ragu, which means the leftover 'mince' would be lovely over spaghetti!
Maddeningly, I couldn't find the book anywhere. I don't know where the heck it could be, because it couldn't have left the house. Regardless, I know their ragu almost off by heart at this point, so the pie proceeded.
The marmite, coco powder and cinnamon are flavourings of my own which I think bring out a deeper flavour, and the parmesan (note that you'll need to source a vegetarian version) really makes the dish.
I used both Quorn and tinned brown lentils for this post, so thats half of each stated, however you can use one or the other if you like!
