Pumpkin, Caramelized Onion & Pine Nut Pasta Bake

"Ooooooh yes sir! This recipe is a winner! Creamy Pumpkin, Caramelised Onion & Pine Nut Pasta Bake! Sounds hard but it's dead easy and ridiculously good. the pumpkin and onions are caramelised until soft and sticky then blended silky smooth with a dash of stock and folded through some 'al dente' pasta with spinach and pine nuts and topped with stringy mozzarella and a good dose of sharp and bitey Parmesan and baked until bubbling and gooey this is next level!!"
