Preheat your oven to 375°F and lightly grease a small oven-safe baking dish with the extra virgin olive oil.
Finely dice the red bell pepper and sauté it in a small skillet over medium heat until tender, adding the spinach at the very end just until wilted.
In a mixing bowl, whisk together the whole eggs, egg whites, sea salt, and black pepper until well combined and frothy.
Lay the turkey bacon slices on a separate parchment-lined baking sheet and brush them lightly with the maple syrup.
Bake the bacon for 5-7 minutes until it begins to crisp, then remove from the oven and roughly chop into bite-sized pieces.
Spread the sautéed peppers and spinach across the bottom of the prepared baking dish, then pour the egg mixture over the top.
Sprinkle the crumbled feta cheese and the chopped maple-glazed bacon evenly over the egg surface.
Place the dish in the oven and bake for 15-20 minutes, or until the eggs are fully set in the center and the top is lightly golden.
