Mist the cups of a silicone muffin pan lightly with cooking spray. Preheat the oven to 350℉.
In a blender, blend together the eggs, cottage cheese, feta, salt, and pepper until smooth.
Divide the egg mixture into the cups of the muffin pan filling each about 3/4ths full. Sprinkle in spinach, mix. Top with the chopped chives. You can add any other mix-ins, such as veggies or bacon, to the cups at this stage.
Bake for 20-22 min or until muffins are slightly firm to touch in the center. Remove the muffin pan from the oven. The egg bites will be puffed up but they will settle down into the cups a bit after removing from the oven. Let the egg bites cool a few minutes before removing them out of the pan.
