Drain artichokes into a bowl, reserving the oil they’re marinated in. Roughly chop artichokes then set aside. Roughly chop the ends and leftover parts of parsnips after spiralizing then add to a food processor and pulse until roughly chopped. Add spiralized parsnips then pulse until noodles resemble rice and set aside. Heat 2 Tablespoons artichoke oil in a large, 12†skillet over heat that’s just a touch above medium. Add mushrooms and leeks, season with salt and pepper, then saute until the vegetables begin to caramelize and brown, 10 minutes. Add an additional 2 Tablespoons oil to the skillet then add parsnip rice, season with more salt and pepper, then saute until al dente, 5-6 minutes. Add chopped artichokes and garlic then saute for 30 seconds or until garlic is very fragrant. Add a squeeze of lemon juice, taste and adjust salt and pepper if necessary, then serve.
