Saut? onion in 1 Tbsp. oil. Add corn and turkey and mix well. Sprinkle with flour. Add milk and Seasoning Mix slowly. Mix well and let stand to cool.
Remove dough and roll out to 3–5 mm / 0.12-0.2 inch thickness. Cut four 4-inch circles for top and bottom crusts. Cut remaining dough into long strips the width and depth of pie pan, and line two 4-inch pans.
Add filling to the lined pans. Brush rims of pies with egg-wash glaze and top with pastry circles. Slightly press rims to seal.
Brush egg wash on top and bake in a preheated 180 °C (355 °F) oven for 25–30 minutes, until golden.
