1. Preheat your oven to 375°F (190°C) and lightly grease a baking dish with olive oil.
2. In a small bowl, whisk together the honey, soy sauce, olive oil, Dijon mustard, minced garlic, pepper, and salt until well combined.
3. Place the chicken breasts in the prepared baking dish, and pour the honey mixture over them, ensuring each piece is well coated.
4. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and no longer pink in the center. A meat thermometer should read at least 165°F (74°C).
5. If you like a bit of caramelization on top, broil the chicken for an additional 2-3 minutes, keeping a close eye to prevent burning.
6. Remove from the oven and let the chicken rest for a few minutes. This helps the juices settle, making each bite incredibly juicy.
7. Garnish with chopped fresh parsley, if using, and serve hot.

Remember, the key here is not to overcrowd the baking dish. Give each chicken breast some space to ensure even cooking.
