Preheat your oven to 350 degrees Fahrenheit.

Generously grease or spray a baking dish with olive or avocado oil to prevent the egg mixture from sticking.

In a large bowl, whisk together the eggs, cottage cheese, salt, pepper, and Italian or Greek seasoning until fully combined.

Stir in the diced bell pepper, chopped spinach, onion, and half the feta. Mix well until all the ingredients are evenly distributed.

Pour the mixture into the prepared baking dish. Give it a quick stir to ensure the vegetables and cheese are well spread. Sprinkle the remaining feta cheese on top of mixture.

Bake for 35 minutes, or until eggs are set and the edges turn golden.

Remove from oven and allow to cool for 10 minutes before slicing into squares. Store in fridge for up to 5 days. I like to reheat in air fryer or toaster oven.
