Preheat your oven to 350°F (175°C) and grease your mini muffin tin.
In a blender or food processor, combine the spinach, eggs, cottage cheese, garlic powder, onion powder, salt, and pepper. Blend until smooth.
Pour the blended mixture into the prepared mini muffin tin, filling each cup to the top.
Sprinkle your cheese on top of each muffin.
Bake for 15-20 minutes, or until the egg bites are set and lightly golden on top.
Allow to cool for a few minutes before removing from the muffin tin.
Serve warm or store in the refrigerator for later.
