Preheat the oven to 375℉.
In a blender or using an immersion blender in a wide-mouth jar, combine all of the Mustard-Shallot Vinaigrette ingredients and blend until smooth. Set aside.
On a small baking sheet, add the panko, parmesan, thyme, parsley, garlic powder, salt, pepper and olive oil. Mix until well combined and spread into a single layer. Transfer to the oven and bake until crisp, 7 to 10 minutes, watching carefully so they do not burn. Remove from the oven to let cool slightly.
Meanwhile, in a large bowl, combine the greens, slaw, pickled onions, and cherry tomatoes. Drizzle with desired amount of the Mustard-Shallot Vinaigrette and toss until well coated.
Divide the salad among 4 plates. Top with the chopped cooked chicken and the Krispies. Drizzle with BBQ sauce and enjoy!
