Note: For timing, I usually start the water to boil for the pasta, then broil the veggies and make the dressing while the veggies are broiling and the pasta is boiling. When I do it that way, this pasta salad is done in about 45 minutes.
Dressing: Shake all ingredients together in a jar or whisk together in a bowl. Taste, and add more salt, sugar, or pepper if you'd like. Set aside until ready to use.
Pasta Salad: Preheat the broiler and arrange the veggies on a sheet pan. Drizzle with the oil and sprinkle with salt. Broil the veggies for 5-10 minutes about 8 inches away from the broiler until slightly charred in places.
Allow the cooked, drained pasta and the broiled veggies to cool for 5-10 minutes, if you have time.
To assemble, add the pasta, veggies, pine nuts, and basil to a large bowl. Pour over about half of the dressing and stir to combine. Taste, and add more dressing to your preference.
Serve immediately or chill covered. Right before serving, season additionally with a little more dressing, pepper, and more herbs, if you'd like. Enjoy!
