Press tin foil on top of the frozen pie crust and place it into the oven to bake for 10 minutes. Remove the foil and continue to bake for 3-5 minutes. Remove from the oven. Place the tin foil on the bottom of a baking sheet. Place the pie crust on top.
Cook the bacon in a large skillet over medium heat until crisp and cooked. Place on a paper towel to drain grease then cut into crumbles.
Combine the eggs, milk, sea salt, and freshly cracked pepper, to taste, together in a bowl and whisk until very well combined.
Sprinkle most of the crumbled bacon in the bottom of the pie crust followed by most of the cheese and chives. Add the well-whisked egg mixture. Sprinkle the remaining bacon, cheese, and chives on top.
Carefully place on a baking sheet and into the oven to bake for 30-35 minutes, or until the top is set and not wiggly and the eggs are cooked through. Don't overcook!
