We love the bite and buckwheat taste of the soba noodles with the parsley pesto, but feel free to substitute whichever pasta you have on hand. The sauce would also be great for dressing chicken, fish, or on salads. *If you have raw pine nuts, to toast, heat a dry pan over medium heat, add pine nuts and toast until golden, shaking the pan frequently to help pine nuts toast evenly. Can be served at warm or at room temperature, depending on your preference.  If serving warm, make sauce first.
