Start by preheating the oven to 375 degrees.
While the oven is heating up, mix the salt, pepper, onion powder, and garlic powder in a small bowl.
Sprinkle the seasoning mixture over the chicken breasts.
Place the chicken breasts on a sheet pan that has been sprayed with cooking spray. You can also lay parchment paper down.
After you have your chicken ready, grab a large bowl and mix the veggies and sweet potatoes with olive oil and salt.
Carefully place the vegetables and potatoes alongside the chicken breast on the sheet pan.
Once you have everything seasoned, place this sheet pan in the oven for about 45 – 50 minutes or until the vegetables are roasted, and the chicken has an internal temperature of 165 degrees.
Serve immediately or store in the refrigerator.
