Prepare the mash: In a large pot of cold salted water, add the diced sweet potato and butternut squash. Bring to a boil and cook for about 20 minutes, until tender.
Drain and transfer to a large mixing bowl. Mash using a potato masher or a fork. It’s okay if there’s still a bit of texture and the mash isn’t completely smooth.
Stir in the soy milk and nutritional yeast. Adjust the salt to taste.
Preheat the oven to 390°F (200°C).
Prepare the filling: Add the TVP to a heat-safe bowl and cover with 1.5 cups (360 ml) of warm vegetable stock to rehydrate. Let it sit for 10 minutes.
Heat the olive oil in a large pan over medium heat. Add the onions and cook for 5 minutes.
Add the corn, red bell pepper, celery, garlic, and jalapeños, and cook for another 10 minutes, stirring regularly.
Add the tomato paste, spices, and flour, and cook for 1 minute, stirring constantly.
Gradually stir in the remaining 1 cup (240 ml) of vegetable stock. Add the black beans and rehydrated TVP, then simmer for 5 minutes. Adjust the salt and pepper to taste.
Assemble: Divide the filling between 4 oven-safe dishes (minimum 20 fl oz each), then spread the mash on top. Optionally, use a fork to create lines on the surface of the mash. You can also use one large oven-safe tray if preferred.
Bake for 35 minutes. Enjoy!

Notes
Gluten-free option: use gluten-free flour
Oil-free option: sautéed the onions in 2 tbsp of vegetable broth.Salt: The saltiness will depend a lot on the broth you use. I recommend going for a low-sodium option and starting with just 1/2 tsp of sea salt flakes. You can always add more later.
