Preheat your oven to 200°C. Add the squash to a baking tray and sprinkle with salt and sage. Drizzle over the olive oil and toss around to coat the chunks. Roast for around 25 minutes or until soft.
Meanwhile, finely slice the shallots. Sauté in the oil until soft and golden and then add the garlic. Soften for another couple of minutes and then add the beans. Season well with salt and pepper and mix with the shallots and garlic.
Once the squash is roasted, leave to cool first if necessary and then add to a blender with the milk, veg stock, nutritional yeast and salt and pepper. Blend until smooth and creamy.
Pour the sauce into the beans and simmer for around 10 minutes, until lovely and thick and creamy and piping hot.
Serve, top with the seeds, sage and cashew parmesan and enjoy!
