Place the chicken in a ziploc bag. Mix the remaining chicken ingredients together, then pour into the bag over the chicken, making sure to coat each piece. Let marinate in the fridge for 2-4 hours. (The longer it marinates, the more flavor will be absorbed.)
In the last half hour, preheat the oven to 350 degrees F.
Combine the oil, lemon juice, and spices for the vegetables. Toss to coat all the vegetables evenly, then spread out in a glass baking dish, making sure to keep them all in one layer.
Remove the chicken breasts from their bag and place on top of the vegetables.
Cover with foil and bake for 30 minutes. OPTIONAL: uncover and broil for the last 2-3 minutes.
Notes
*Prep time does not include marinating the chicken.
