Preheat your oven to 350°F and lightly grease a muffin tin with the olive oil to prevent sticking.
In a skillet over medium heat, cook the ground turkey until browned and completely cooked through, then set aside to cool slightly.
Finely chop the fresh baby spinach and red bell pepper into small, uniform pieces.
In a large mixing bowl, whisk together the eggs, liquid egg whites, sea salt, black pepper, and garlic powder until the mixture is well combined and frothy.
Fold the cooked turkey, chopped spinach, and bell peppers into the egg mixture until evenly distributed.
Divide the mixture evenly among the muffin tin slots, filling each about three-quarters full.
Bake for 20 to 25 minutes or until the muffins are set in the center and the tops are slightly golden.
Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack or storage container.
Serve warm or cold with fresh avocado slices on the side for a boost of healthy fats.
