Prepare California Pizza Kitchen Dijon Balsamic Vinaigrette according to the recipe linked to in the Box below.
In a large bowl (you will be adding the vegetables in a few minutes, so make sure it is large enough to hold them) add 6 tablespoons extra virgin olive oil, soy sauce, cumin and cayenne. Whisk to combine. Set aside.
Place prepared eggplant, asparagus, zucchini and scallions in the marinate. If using unroasted corn, add these, too.
Allow to marinate on the counter for at least 30 minutes.
Preheat a grill to medium hot. (Alternately, use an indoor grill, like a George Foreman)
Remove vegetables from marinade and place in a grilling pan or basket with holes small enough to hold the corn, if using, and all other pieces.
Place pan or basket on grill and roast, shaking frequently, until all vegetables have a nice roasted char.
Remove from grill. Place on a plate and set aside.
Starting at the top, with a very sharp knife, cut down into each avocado until you hit the pit. Cut completely around the avocado, top to bottom, touching the pit the entire time.
Pull the two halves of the avocado apart and remove the pit with a spoon.
Use the spoon to scoop the avocado out of the skin. Cut into large bite-sized chunks. Set aside briefly.
Mound Romaine lettuce in 2 large or 4 medium-sized bowls or plates.
Scatter grilled vegetables equally over top of each salad.
Cover each salad with avocado chunks.
Sprinkle with sun-dried tomatoes.
Drizzle with prepared California Pizza Kitchen Dijon Balsamic Vinaigrette.
Serve immediately.
