Anyone can use natural, mainstream ingredients for a centrepiece instead of Tofurky.
No offence to the fake meat industries, but I know some plant-based health nuts and omnivorous folks who feel more comfortable with familiar ingredients. This is why we need to consider homemade centrepiece roasts when preparing for festivities.
Here are some foods that contribute to meatiness in a loaf without any animals.
Mushrooms
These fungi are tough and textured. Flavour them with smoky and umami tastes. Cook the moisture out and let the mushies sear.
Walnuts
Aside from providing omegas and more, walnuts will bulk out a roast.
Lentils
Green lentils are wonderfully cheap. Whichever diet you prefer, these legumes will bulk out your meal.
