I took inspiration from the master chef himself-jamie oliver's mint pesto sauce, where i have used mustard greens (leaf) or as we refer to it in nepali as 'rai ko saag' instead of mint to make the pesto which i thought would make a healty and tasty spaghetti dish. I hope you will enjoy the flavors! foodrevolutionday2016 jamiesitalianindia betterbutter.
