Preheat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil.
In a large mixing bowl, combine the cottage cheese, cheddar cheese, spinach, bell peppers, tomatoes, onion, garlic powder, onion powder, salt, black pepper, and red pepper flakes. Mix well until all ingredients are evenly distributed.
In a separate bowl, whisk the eggs until well beaten. Pour the eggs into the cheese and vegetable mixture, stirring until fully combined.
Pour the mixture into the prepared baking dish, spreading it out evenly.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the center is set.
Remove from the oven and let it cool for 5-10 minutes. Garnish with chopped parsley before serving.
