Preheat the oven to 400*F.
Spread the chicken, potatoes, onion, and carrots evenly across the pan.
In a small bowl whisk honey, brown sugar, and mustard until combined well. Brush the mixture atop the chicken breasts.
Drizzle olive oil over the veggies and chicken. Cook for 25 minutes.
Take out of the oven and flip the veggies. Arrange the broccoli and asparagus evenly across the tray.
Drizzle olive oil once more and place in the oven for 5-10 more minutes (or until chicken is thoroughly cooked).
