If using raw chicken, saute until cooked.( I use either a rotisserie chicken from the deli at my local grocers or 2 cans of chicken from Sam's or COSTCO) Soften the onion in the microwave till very soft. In a saucepan heat the margarine till melted and add the four and spices and mix till thick and bubbly. Add the milk and broth and cook till thick creamy. Stir and cook for 2 more minutes. Add the chicken and veggies, pour into the crust, cover with the top crust, slit and bake at 425* for 30-35 minutes or until golden brown.
