Heat oven to 450°F. Remove pie crust from pouch; onto ungreased cookie sheet, unroll crust.
With sharp knife, cut jack-o'-lantern face from crust. If desired, place cutouts on crust to decorate, securing each with small amount of water. Bake 9 to 11 minutes or until crust is light golden brown.
Meanwhile, in 10-inch nonstick skillet, cook sausage and onion over medium-high heat 8 to 10 minutes, stirring frequently, until sausage is no longer pink. Stir in remaining ingredients except cilantro. Heat to boiling. Reduce heat to medium-low; simmer uncovered 8 to 10 minutes, stirring occasionally, until corn is cooked and sauce is desired consistency.
Stir cilantro into sausage mixture. Carefully place warm baked pie crust over turkey mixture in skillet.
