I actually did try out Vegan Dad's awesome roast!
Here's what I put in the stuffing:
1/2 cup cooked wild rice (I cooked the whole packet and then measured the rice afterwards)
1 cup cubed sweet potato
1 sliced leek (it's still around! WOOOOO!!!)
2tsp garlic
Thyme and Rosemary (it was either that or Thyme and Oregano - I can't remember!)
1/4 cup water
1 cup walnuts cut into teeny tiny pieces
2 T olive oil
Salt and pepper to taste.
Method: Fry up the potato, leek and garlic in olive oil. Once it's starting to brown add in everything else. Cool and stuff into the roast as per Vegan Dad's directions.
This will fall apart, but it is tasty!

Drowned in gravy:

It was pretty good. I'm going to tweak the roast - I can't find poultry seasoning (the original recipe calls for this), so I'm going to try some of the Massels 'chicken' stock.
What's everyone else planning for Christmas lunch/dinner?
