Step 1

Preheat an oven to 400 degrees F (200 degrees C). Whisk the flour, baking powder, and salt together in a small bowl; set aside.

Step 2

Beat the eggs in a mixing bowl until smooth. Whisk in the flour mixture until no lumps remain. Stir in the Colby-Monterey Jack cheese, cottage cheese, spinach, green chiles, and melted butter until evenly blended. Divide the mixture between the pie crusts.

Step 3

Bake the quiches in the preheated oven for 15 minutes at 400 degrees F (200 degrees C), then reduce the temperature to 350 degrees F (175 degrees C). Continue baking until the quiches are lightly browned and a knife inserted into the center comes out clean, 35 to 40 minutes.
