Preheat your oven to 375°F and lightly grease a small oven-safe baking dish with the olive oil.
In a medium mixing bowl, whisk together the eggs, cottage cheese, sea salt, black pepper, and garlic powder until well combined and slightly aerated.
Roughly chop the fresh spinach and finely dice the red bell pepper into uniform pieces.
Fold the chopped spinach, diced red bell pepper, and crumbled feta cheese into the egg and cottage cheese mixture.
Pour the prepared mixture into the greased baking dish, ensuring the vegetables are distributed evenly.
Bake for 25 to 30 minutes, or until the edges are golden and the center is set and no longer jiggles.
Remove from the oven and let the bake rest for 5 minutes before slicing into portions.
