Preheat your oven to 400°F.
Toss the sweet potatoes with olive oil, paprika, garlic powder, salt, and pepper. Spread them on one side of a sheet pan.
Toss the zucchini with olive oil, salt, and pepper. Spread them on the other side of the pan.
Back the sweet potatoes and zucchini for about 10 minutes before adding cubed chicken to the pan.
Dice the chicken breasts and season with olive oil, garlic powder, Italian seasoning, salt, and pepper. Place them in the center of the pan.
Bake for 20-25 minutes, or until the chicken is cooked through (165°F internal temp) and the sweet potatoes are tender.
