Make the vinaigrette - click up above for the recipe.
Heat the tortilla in a microwave for 10 seconds so it becomes pliable.
Combine the roasted chicken, mixed greens, kalamata olives, red onion, feta cheese, grape tomatoes, and Fran's Vinaigrette into a bowl. Drizzle with a bit of the vinaigrette, to taste then season with a little sea salt and freshly cracked pepper. Toss to coat evenly and place into the center of a flour tortilla. Roll then cut in the center at a diagonal. Serve immediately. Enjoy.
