There is almost always a jar of tapenade in the refrigerator, just as there should be one in yours. It is like a magic wand in the kitchen, able to take disparate ingredients and turn them into a trip to far off lands. To get the right kind of sear on this dish, you want to use your biggest pan, like a 14-incher. If the vegetables are too close they will just steam and get mushy, so if you do not have a big pan, do this in a couple pans or batches.
