My all time favorite sauce to add to a spinach and ricotta ravioli. An absolutely quick, rich and delicious sauce to make that will be a winner on those meat free days. Just biting into this pasta with this sauce and having that crunch of pine nuts and some heat of chilli is heaven all at once. Basil pesto spring onion and chive sauce for you to make at home and to forget about buying those packet sauces ever again.
