Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine honey, Dijon mustard, olive oil, garlic powder, onion powder, dried thyme, salt, and pepper. Mix well to create a marinade.
Add the chicken thighs to the marinade and coat them thoroughly. Set aside to marinate for at least 10 minutes.
In a baking dish or a large skillet, add the diced potatoes and the mixed beans. Drizzle with olive oil and season with salt and pepper.
Nestle the marinated chicken thighs on top of the potato and bean mixture.
Pour any remaining marinade over the chicken thighs and vegetables.
Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.
After 25 minutes, remove the foil and continue baking for an additional 20 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Once cooked, remove from the oven and let it rest for 5 minutes. If desired, garnish with fresh parsley before serving.
