Heat the oil in a large sauté pan over medium-high. Add the asparagus and sauté until slightly tender, 3 minutes. Add the garlic; bloom 30 seconds. Add the remaining chopped garden greens and sauté until wilted, 2 minutes. If you need to add a little water to help it along, don’t! Just kidding, you totally can. Season with a little salt and pepper.
And the walnuts.
