Delicious roasted potatoes with peppers and onions.
Preheat your oven to 400 degrees Fahrenheit. Spray a half-sheet pan liberally with non-stick spray.
Cut the potatoes into 1" x 1/2" pieces. Slice the onions into 1/2" wide strips. Slice the peppers into 1/2" wide x 1 1/2" long pieces. Add the vegetables to the pan.
Whisk the Magical Seasoning Blend and the poultry seasoning together, then add the mustard and oil and mix again.
Pour the liquid mixture over the vegetables, then mix well until all the vegetables are evenly coated.
Roast the vegetables for 20 minutes, stir, and roast for another 20 minutes. Test for doneness by poking a few of potato pieces with a fork. If they are not tender, roast for an additional 5 to 15 minutes until they are done.
Broil the vegetables for 5 to 15 minutes, until they are golden brown and getting a bit of char. Serve as desired.
