To cook the asparagus, place a splash of olive oil along with a couple pinches of salt in a large skillet over medium-high heat. When the pan is hot add the asparagus and broccolini. Toss well and cover the skillet with a lid. Cook for one minute. Stir again, taste a piece, and cover again for another minute - but only if needed. You don't want to overcook the vegetables here, they should be bright and with a bit of bite to them. When the vegetables are cooked, remove them from the heat and stir in the radishes and lemon zest. Taste, add a bit of salt if needed. Toss with 1/3 of the pine nut dressing, adding more as needed - as I mention up above, you might have a bit extra.
