Preheat oven to 375 F and line muffin tin with parchment paper liners. Set aside.
In a large bowl, add eggs, cottage cheese, salt and pepper. Whisk with a fork.
Then add bell pepper, spinach and cheese. Whisk again.
Divide egg mixture evenly between openings of a muffin pan, filling each one almost full. Bake for 23 minutes or until toothpick inserted in the middle of center comes out clean and egg muffins have puffed up.
Remove from the oven and enjoy.
