Preheat oven to 425 degrees F and line a very large sheet pan with parchment paper and set aside.
Prep the chicken and veggies: First, pierce the sweet potato with a fork a few times and place in the microwave for 5 minutes, flipping on the other side after 2.5 minutes. Remove and let cool for a minute. Peel off the skins and then chop into very small pieces (important they are small and that you first microwave for these to be cooked in time with everything else!)
Chop the chicken into 1/2 inch pieces. Remove the stems and seeds and coarsely chop the peppers. Cut the beans in half. Coarsely chop the broccoli.
Place veggies and chicken on the sheet pan.
In a small bowl, combine the olive oil and all of the seasonings listed and mix.
Pour seasoning mixture over the veggies and chicken on the sheet pan and toss with your hands until everything is well coated.
Bake for 10 minutes, then flip and bake for another 10-20 minutes. (Amount of time depends on the size you’ve cut your veggies and chicken and the heat of your oven.)
Optional: Remove from the oven then top with cheese. Return to the oven for 1-2 minutes or until cheese is melted.
