Pound the chicken breast to achieve an even thickness for uniform cooking. Season lightly with salt and pepper.
Prepare a dredging station with three shallow bowls: one with all-purpose flour, one with the lightly beaten egg, and one with panko breadcrumbs.
Coat the chicken breast: first dredge in flour, then dip in egg wash, and finally press into the panko breadcrumbs to adhere.
Preheat your air fryer to 400°F. Lightly spray the breaded chicken with a cooking spray for extra crispiness.
Place the chicken breast in the air fryer basket and cook for 10-12 minutes until golden brown and cooked through, turning halfway to ensure even crisping.
Meanwhile, make the creamy slaw by finely shredding the cabbage and carrot. In a bowl, toss them with non-fat Greek yogurt, and season with a pinch of salt and pepper.
Toast the whole wheat bun lightly in a pan or toaster for added texture.
Assemble the sandwich by placing the crispy chicken on the bun and topping it with a generous serving of the creamy slaw.
Serve immediately and enjoy your balanced, crispy air-fried chicken sandwich with creamy slaw.
