Use a bottled Greek or Caesar dressing instead of making a vinaigrette to save even more time.
Preheat oven to 450°.
Place pizza crust on a baking sheet; bake at 450° for 8 minutes. Cut crust into 1-inch pieces.
While crust bakes, combine lettuce and next 7 ingredients (lettuce through feta cheese) in a large bowl. Combine vinegar and remaining ingredients, stirring with a whisk.
Add crust pieces to lettuce mixture; toss gently. Drizzle vinaigrette over salad; toss gently to coat.
