Preheat your oven to 400°F (200°C).
In a mixing bowl, whisk together honey, Dijon mustard, olive oil, salt, and pepper to create the honey mustard marinade.
Place the chicken breasts in a baking dish and pour half of the honey mustard marinade over them, ensuring they are well coated. Reserve the other half for serving.
In a large skillet, heat olive oil over medium heat. Add the halved baby potatoes and season with salt, pepper, garlic powder, thyme, and paprika. Sauté for about 5 minutes, until they are slightly browned.
Transfer the sautéed potatoes to the baking dish around the chicken.
Place the baking dish in the preheated oven and bake for 25 minutes.
After 25 minutes, add the drained beans to the baking dish, mixing them in with the potatoes and chicken.
Continue to bake for an additional 10-15 minutes, or until the chicken is cooked through (internal temperature should reach 165°F or 75°C).
Once done, remove from the oven and drizzle the reserved honey mustard sauce over the chicken before serving.
Garnish with fresh parsley if desired and enjoy your meal!
