Step 1

Preheat oven to 425°F. Heat oil in a large skillet over medium-high. Add beef and onion; cook, stirring to crumble, until onions are softened and meat is browned, about 5 minutes. Stir in taco seasoning and salsa until combined. Cook 2 minutes, and remove from heat.

Step 2

Place 1 pie crust in bottom of a pie plate. Spread refried beans evenly over crust; sprinkle with 1/2 cup of the cheddar. Top with beef mixture, and then spoon green chiles evenly over beef mixture; sprinkle with remaining cheese. Top with remaining pie crust; lightly press edges of crust together to seal.

Step 3

Bake in preheated oven 30 minutes, tenting edges with foil during the last 10 minutes if crust becomes too brown. Let stand 10 minutes before serving. Serve with desired toppings.
