Preheat the oven to 400°F (200°C). Spray a baking dish with nonstick cooking spray.

Season the chicken breasts with salt and pepper and place them in the prepared dish.

In a small bowl, whisk together soy sauce, honey, and minced garlic until combined.

Pour the marinade over the chicken, ensuring it’s well-coated. Let it marinate for at least 15 minutes.

Bake the chicken for 25-30 minutes or until it reaches an internal temperature of 165°F (74°C). Remove from the oven and let cool slightly before shredding with two forks.

Warm taco shells according to package instructions. Fill each shell with shredded chicken and top with lettuce and diced tomatoes.
