Ever since I was a kid, my mum, my sister and myself have made this pasta bake recipe. I hadn't made it for years until the other night, and fancied it so decided to give it a go but with some slight differences to our childhood recipe! It's pretty easy to prepare and cook so it's good if you want something done in just an hour or so. The butternut squash offers a nice sweetness, which is complimented by the earthiness of the mushrooms, nuttiness of the gruyere, other veg and the chorizo adds a nice smokey/spiciness to the dish, though the chorizo can easily be omitted if you're a vegetarian. I'm not hugely specific with ingredient measures, so you can adapt the recipe to your own tastes/preferences if desired.
