Spray your roasting pan with non-stick cooking spray, then slice your onions, and cut up your carrots and potatoes. The onion slices should be about 1/2 inch wide. The carrot sticks should be about 1/3" thick and about 3" long. The potatoes should be cut into 1" chunks. Add cut up vegetables to the roasting pan as you go.

Whisk the Magical Seasoning Blend, poultry seasoning, Dijon mustard, 2 tsp of lemon zest, and the oil together in a medium-sized bowl. Whisk in the lemon juice.

Pour the mixture over the vegetables in the pan.

Separate any large chunks of onion into slices, then toss the lemon mixture and the vegetables together until all the vegetables are evenly coated.

Roast at 400 degrees for 20 minutes. Add the frozen green beans to the other vegetables and stir to combine. 

Roast for 20 more minutes, then stir again. Roast for 20 more minutes.

Stir again, then put the pan under the broiler until the vegetables are golden brown. Remove from the oven.

Garnish with the remaining lemon zest and some chopped chives or parsley.
