Bake pie crust according to package instructions. Set aside to cool. Cook spinach according to package instructions and drain well. In a large bowl, combine spinach with the next six ingredients. Preheat oven to 350°F. With a fork, gently spread the hash evenly over the cooked pie shell. Spoon spinach mixture over hash. Bake for 35 minutes. Remove from oven and sprinkle the cheese over the top. Bake another three to five minutes, or until cheese is hot and bubbly. Serve warm or cool.
Bite-Sized Bliss: With a few adjustments, this quiche makes great finger food. Double the recipe and press pie crusts into a 9 x 12-inch foil pan. Prepare as directed. When cool, cut into two-inch squares and serve individually in cupcake wrappers.
