Dandelion greens are one of my favorite edible weeds, and they love being wilted into garlic butter with pasta. I decided to add some sweet potato leaves, mostly because they pop up and kind of go crazy in my garden every year, but also because they add a bit of sweet, more delicate green flavor to offset the dandelion. If you eat dairy, feel free to use grass fed butter of ghee for your cooking fat, and substitute real parmesan for the pistachio parmesan. Having said that, the pistachio parmesan is a lot more nutritious, delivering healthy fats, complete protein, and fiber; and it adds a comforting earthiness to the dish.
