Preheat the oven to 350°F (175°C) and lightly coat a baking dish with cooking spray.
In a mixing bowl, combine cottage cheese, eggs, chives, salt, and pepper. Add optional ingredients if desired and mix well.
Pour the mixture into the baking dish and spread it out evenly.
Bake for 25-30 minutes until the eggs are set and edges are golden brown.
Let it cool for a few minutes before serving.
