Preheat oven to 375°F.

Mix together paprika, garlic powder, onion powder, ground thyme, ground black pepper, cayenne pepper, dried basil, dried oregano, cumin powder, and salt in a small bowl to make blackening seasoning.

Brush chicken breast with 1 tablespoon of extra virgin olive oil on both sides.

Season both sides of the chicken with blackening seasoning.

Heat the remaining 1 tablespoon of oil in a skillet over medium-high heat.

Cook chicken on each side for 7 minutes until blackened.

Transfer the skillet to the preheated oven and bake for 15 minutes, or until chicken is cooked through.

Allow the chicken to cool slightly.

Dice the cooled chicken into small pieces.

In a large bowl, combine the diced chicken, red onions, grated carrot, and scallions.

In a separate bowl, whisk together mayonnaise, apple cider vinegar, and Dijon mustard to make the dressing.

Pour the dressing over the chicken mixture and stir to combine thoroughly.

Serve as a sandwich filling or on its own.
