Add all dressing to a small jar or a bowl. Shake or stir to combine, then set aside.
Cut any brown ends off of broccolini, then place in a large mixing bowl. Toss with 2 tablespoons of olive oil and a generous amount of salt and pepper. Broccolini should be well-coated in the oil.
Next, heat either your BBQ or a cast iron grill pan to medium-high. Once hot, place the tossed broccolini directly on the grill gates. Cook for approximately 6-10 minutes, tossing every couple minutes, or until broccolini reaches your desired char level. Remove broccolini from heat when done.TIP: broccolini can have either thick or thin stems; the thicker the stem, the longer it will take to cook. If you are using a grill pan, you will need to work in BATCHES, which will also take a bit longer. Covering the grill or grill pan with a lid can help speed up the process!NOTE: You are looking to have the broccolini be lightly charred/browned and tender enough to eat, while still maintaining a nice crunch.
Place grilled broccolini onto a large serving plate. Drizzle salad dressing over top, and sprinkle with shaved parmesan, chopped basil, and red pepper flakes. Toss everything together, adjusting seasonings to taste. Serve and enjoy!
