I need a vegan sauce to go with gnocchi?

[Bathsheba]

I'd dice a pumpkin roast until caramelized (toss in olive oil first, maybe add a few sprigs of rosemary and a pinch of salt) in a hot oven. While that is cooking finely dice and fry some shallots (the purple ones) or just some onions. Add some garlic and seasoning (salt and black pepper). If your sis likes spicy food then add a pinch of cayenne/chilli. Add about half a tin of diced tomatoes. Cook until the shallots/onions look soft and transparent. Dry roast (ideally on a cast iron pan) a handful of pine nuts, then set aside for garnishing. When everything is cooked toss together with an extra splash of virgin olive oil. Sprinkle the pine nuts on top just before serving with a generous quantity of finely chopped parsley. My family love this. I find the pumpkin breaks down and clings to the pasta really well... meaning you don't need cream etc.
