Steps
1. Preheat your oven to 375°F (190°C).
2. In a small bowl, mix together the Dijon mustard, honey, and olive oil until well combined.
3. Season the chicken breast with salt and pepper on both sides.
4. Place the chicken in a baking dish and pour the honey mustard mixture over the top, ensuring it is well coated.
5. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and juices run clear.
6. Remove from the oven, let it rest for a few minutes, then slice and serve, garnished with fresh parsley if desired.
