I found these two GH nut roast recipes, they may not be the one you had but might be worth a try.

I make lovely nut roast but I never write the recipes down and I make them in bulk so the quantities are quite large. Nut roast freezes really well.
This is a very rough recipe idea.
One finely diced onion
500 - 700g mushrooms very finely diced (whatever you fancy)
Garlic - at least 3 or 4 cloves but add more or less according to preference
800g nuts of your choice, chopped in the food processor
200g panko bread crumbs
200g pecorino or grana padano finely chopped in food processor
Eggs to bind usually 3 or 4 for this quantity, the mixture needs to be what can only be described as stodgy!
Seasonings and flavourings can be whatever takes your fancy. I've used ginger, soy sauce, veg oyster sauce (leave the cheese out for this one) chilli, sun-dried tomatoes, various different herbs (oregano and sage are favourites), veg stock cube, Worcestershire sauce (veggie version), mustard, tomato puree. I sometimes line the base of the tin with a suitable roasted root vegetable (you can add a little maple syrup to them) or if it's a summery one to serve with salad I add a layer of roasted peppers or s/d toms and sliced mozzarella with a little bit of pesto.
The most important thing is to take it out of the oven and leave it in the tin for 10 mins before you slice it. Work out a good basic recipe which slices well and then let your imagination run wild.
