- Preheat oven to 425°F. Toss bell peppers, onion, broccoli and olive oil together in a large bowl until coated. Season with salt. Arrange vegetables and chicken in a single layer on rimmed baking sheet.
- Bake flipping halfway through, until vegetables are tender and chicken is fully heated through, about 15 to 20 minutes. Serve and enjoy.
Tip: Packaged sliced bell peppers, red onions, and broccoli florets can usually be found in the produce aisle of your local grocer.
