Preheat your oven to 350°F (175°C) and lightly grease a standard muffin tin with a touch of olive oil or parchment liners.
Heat the teaspoon of olive oil in a small skillet over medium heat, then add the ground turkey and cook until browned and fully cooked through, breaking it into small crumbles as it sears.
While the turkey cooks, finely chop the baby spinach and the red bell pepper into small, uniform pieces.
In a large mixing bowl, whisk together the 2 large eggs and the liquid egg whites with the sea salt, black pepper, and garlic powder until the mixture is light and frothy.
Fold the cooked turkey crumbles, chopped spinach, and diced bell peppers into the egg mixture until evenly distributed.
Carefully pour the egg and turkey mixture into the prepared muffin cups, filling each about three-quarters of the way to the top.
Sprinkle the shredded sharp cheddar cheese evenly over the top of each muffin cup.
Bake for 20 to 25 minutes, or until the eggs are firm to the touch and the cheese has melted into a beautiful golden crust.
Allow the muffins to cool in the tin for 5 minutes before using a knife to gently loosen the edges and serve warm.
