PREPARATION
Preheat oven to 425°.
Bring Knorr® Leek recipe mix, water and milk just to a boil over medium-high heat in 4-quart saucepan, stirring occasionally. Reduce heat to low and simmer, stirring frequently, 5 minutes. Stir in vegetables, chicken, thyme and, if desired, ground black pepper. Simmer, stirring occasionally, 5 minutes or until heated through. Stir in cheese until melted. Evenly spoon into two 9-inch pie plates.
Top each with pie crust. Press pie crust around edge of pie plates to seal; trim excess pastry, then flute edges. Make small slits in pastry with tip of knife. Bake 20 minutes or until crusts are golden.
FREEZING/MAKE-AHEAD DIRECTIONS: Prepare as above but do not bake. Wrap in heavy-duty aluminum foil and freeze. To bake, preheat oven to 375°. Remove from freezer and remove foil. Wrap edges of pie shell with foil. Bake 50 minutes. Remove foil and bake an additional 20 minutes or until crust is golden.
