When all the chicken is browned, add the onion, potatoes, baby carrots, and scallions. Stir a few times to combine well. Add the Seasoning into the pot, stir to blend well with all the ingredients. Cover the pot reduce the heat to medium-low, stirring now and then. Cook for about 45-60 minutes or until the chicken is cooked through and the potatoes are tender.
