Preheat the oven to 425.
Heat the skillet at medium.
Spray skillet with cooking spray, or put in a little oil.
Add 1 1/4 lb. boneless chicken that has been sprinkled with Cajun Blackening Seasoning. I used this:
Brown chicken on both sides.
Meanwhile, mix in a separate bowl:
2 small potatoes, cut up,
2 cut up peppers,
One package (12 oz?) baby bella mushrooms, sliced,
2 Tbs oil,
and 1 Tbs seasoning. (Remember the WOW seasoning that I talked about with the skillet potatoes?)
Remove out the chicken from the pan, and put the vegetable mixture in the bottom of the pan. Top the vegetables with the chicken.
Bake for 45 minutes. Check for with an instant read thermometer to ensure the chicken has reached 180 degrees.
Serve. Have parmesan cheese on the side for people like me who like parmesan on almost everything. Serves 3-4.
