quinoa stuffed acorn squash with pipian rojo on a white plate

Have you ever had roasted acorn squash?? The roasting brings out the sweetness of the squash and it just begs to be filled with all sorts of veggie goodness. This quinoa stuffed acorn squash is studded with sautéed wild mushrooms and topped with a pipian rojo.

Pipian rojo is a hearty, stick to your ribs kind of sauce, made with roasted pumpkin seeds, roasted tomato, and dried pasilla, arbol, and ancho chiles. It pairs perfectly with the umami of the mushrooms and provides a touch of creaminess to the whole dish. The pipian is a recipe from the excellent book Decolonize Your Diet, which I highly recommend.

I was supposed to publish this recipe before Thanksgiving since it would make a great vegan Thanksgiving main course, but of course, life got in the way and I couldn’t publish it in time. We hosted Thanksgiving at our house this year, and it was so good to be surrounded by all the craziness and noise that family brings.

Our feast was a mix of both vegan and omni dishes. My husband (who is not vegan) was adamant that there needed to be turkey so we compromised and almost all the sides and desserts were vegan.This was my first time trying a vegan celebration roast!! I’m not going to lie, I was a little worried. I ended up buying two, the Gardein Holiday Roast and the Field Roast Hazelnut Cranberry Roast en Croute.

The Gardein Roast is more turkey-like and filled with sort of stuffing. The Field Roast Cranberry Roast is more sausage-like with ginger, cranberries, and apples. The baby and I enjoyed both of them very much. I was very surprised and thrilled when one of my sisters had celebration roast instead of turkey!! After trying both of them, I can’t decide which one I like best, they’re both really good. I do have to say that If you’re more into turkey-like meats then go with the Gardein Roast, if you’re more of a sausage person then go with the Field Roast. How great is it that vegans and vegetarians have so many delicious options available!I’m definitely getting a celebration roast for Christmas.
