01 - Preheat oven to 350°F. Grease a 12-cup muffin tin generously with non-stick spray or line with silicone muffin liners for easy removal.
02 - Add eggs, cottage cheese, milk, salt, pepper, and garlic powder to a blender. Blend on high speed until completely smooth and frothy, about 30-45 seconds.
03 - In a large mixing bowl, combine the chopped spinach, diced red bell pepper, sliced green onions, and shredded cheddar cheese. Toss evenly to distribute.
04 - Pour the blended egg mixture over the vegetable and cheese blend. Using a spatula, fold gently until all ingredients are evenly incorporated.
05 - Divide the mixture evenly among the 12 muffin cups, filling each approximately three-quarters full. The batter will puff slightly during baking.
06 - Bake for 18-22 minutes, or until egg bites are completely set in the center and lightly golden brown on top. A toothpick inserted should come out clean.
07 - Let cool in the muffin tin for 5 minutes. Run a thin knife around the edges of each cup to loosen, then gently lift out. Serve warm or allow to cool to room temperature.
