Place pie crusts in two pie pans. Line crusts with aluminum foil. Bake both pie crusts at 400°F for 5 minutes; remove foil and bake an additional 5 minutes. Add chili powder, cumin, and cheeses to bottom of baked crusts.
Mix together eggs, milk, chilies, onions, olives, and cilantro in a large mixing bowl. Pour half in each pie crust.
Place one pie on baking sheet and bake at 400°F for 30 minutes. Add foil to edge of crust as crust starts to brown. Continue to bake until knife inserted in center comes out clean. Remove from oven and allow to set up for about 5 -10 minutes before serving.

Line edges of crust with foil as crust starts to brown. Continue baking about 30 minutes until knife inserted in center comes out clean. Let set for 10 minutes before serving.”)
