Heat oven to 425°F. Make pie crusts as directed on box for Two-Crust Pie using 9 1/2- or 10-inch deep-dish glass pie plate.
Spray 12-inch skillet with cooking spray; heat over medium-high heat until hot. Add pork and onion; cook 3 to 5 minutes, stirring occasionally, until pork is no longer pink.
Add tomatoes, corn, green chiles, chili sauce, olives, raisins, cumin and salt. Heat to boiling. Reduce heat to medium; simmer 5 minutes, stirring occasionally, until slightly thickened. Remove from heat; cool 5 minutes.
Spoon mixture into crust-lined pie plate. Cut 4 wide slits or small designs in second crust; place crust over pork mixture. Seal edge and flute edge. Brush crust with milk; sprinkle with cornmeal.
Bake 25 to 35 minutes or until deep golden brown. Cover crust edge with 2- to 3-inch-wide strips of foil after 10 to 15 minutes of baking to prevent excessive browning. Let pie stand 5 to 10 minutes before serving.
