Season both sides of chicken liberally with salt, pepper, granulated onion, granulated garlic, paprika and oregano.
Set a large skillet over medium-high heat. Once hot, drizzle in a tablespoon of olive oil and lay the chicken, skin side down, in a single layer. Allow to cook, untouched, until deeply golden brown, about 5 to 8 minutes. Flip over and continue to cook on the second side until the chicken has cooked through, about 5 minutes longer. Transfer the chicken to a plate and set aside.
Drizzle in the remaining 2 tablespoons of olive oil to the skillet and add the torn bread pieces. Season lightly with a bit of salt and pepper and cook, tossing often, until the croutons have browned. Remove from the heat and set aside.
In a very large bowl, toss together the arugula, farro, radish, tomatoes, shallot, parmesan, pistachio, parsley and basil. Slice the chicken on an angle and add to the bowl.
To make the dressing, combine the olive oil, vinegar, mustard, parmesan, garlic, Italian seasoning, red pepper flakes and a pinch of salt and pepper in a mason jar with a tight-fitting lid. Shake vigorously until well combined.
Add as much dressing to the salad as you'd like and give it a toss. Serve immediately and enjoy!
