Glad you found a recipe Ethel - I have had a good look in my Rose Elliot book on veg. cooking and there isn't one recipe for nut roast!
The nearest is pimento and chestnut casserole:
In a flameproof casserole sauté in veg oil 2 onions, chopped, head of celery, chopped, can of red peppers (or 2 fresh ones), 4 tomatoes.
Add 2 cans whole chestnuts, 2 tbsp flour and 1 pint red wine. S&P.
Bake at 350F, gas mark 4, for 45 minutes.
You can substitute mushrooms for the peppers.
I recommend this book "Not just a load of old lentils". It's quite old, but I bought it on Amazon recently for about £2 - I used to have a copy ages ago.
We're eating much less meat these days so I often make a veggie recipe.
