Hash Brown Quiche Cups

1 large egg
1/4 teaspoon salt
1/8 teaspoon pepper
2 cups frozen shredded hash brown potatoes, thawed
1/4 cup shredded Asiago cheese
Filling:
3 large eggs
1 tablespoon minced fresh chives
1/3 cup shredded Colby-Monterey Jack cheese
1/3 cup fresh baby spinach, thinly sliced
2 bacon strips, cooked and crumbled

Preheat oven to 400°. Grease 8 muffin cups.
In a bowl, whisk egg, salt and pepper until blended; stir in potatoes and Asiago cheese. To form crusts, press about 1/4 cup potato mixture onto bottom and up sides of each prepared muffin cup. Bake until light golden brown, 14-17 minutes.
For filling, in a small bowl, whisk eggs and chives until blended; stir in cheese and spinach. Spoon into crusts; top with bacon. Bake until a knife inserted in the center comes out clean, 6-8 minutes.
