For the filling, heat the oil in a sauté pan and cook the onions, carrot and celery until tender. Add the garlic and mushrooms and cook for a further 10 minutes or until tender. Add the stock, lentils and soy sauce. Bring to the boil, taste for seasoning then put into the dish. Top with the mash.
Heat the oven to 200C, gas 6. Bake until piping hot and the mash has browned slightly – about 30 minutes.
