Preheat the oven to 350°F. Place the pie crust on the baking sheet and dock the bottom with a fork. Set aside.
Sprinkle ½ of the cheese and ½ of bacon on the bottom of the crust.
In a medium-size mixing bowl, whisk together the eggs, half & half, chives, garlic salt, mustard, pepper, onion powder and nutmeg until; fully combined.
Add the remaining crumbled bacon to the egg custard and stir. Pour into the pie shell.
Top with remaining cheese.
Place into the oven and bake for 45-50 minutes or until lightly golden and the center is set when gently shaken. Check at 30 minutes and lay a piece of foil in top to prevent over browning, if needed.
Allow to rest on the counter for 30-60 minutes before attempting to cut.
Serve warm or at room temperature.
