01 - Preheat your oven to 350°F. Grease a standard 12-cup muffin tin 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 seconds.
03 - In a large mixing bowl, toss together the chopped spinach, diced red bell pepper, sliced green onions, and shredded cheddar cheese until evenly distributed.
04 - Pour the blended egg mixture over the vegetables and cheese. Using a spatula, fold gently to combine without over-mixing.
05 - Divide the filling evenly among the prepared muffin cups, filling each approximately three-quarters full. The mixture will puff slightly during baking.
06 - Bake for 18 to 22 minutes, or until the egg bites are fully set and the tops are lightly golden. A toothpick inserted into the center should come out clean.
07 - Let the egg bites cool in the tin for 5 minutes. Run a thin knife around the edges of each cup to loosen, then carefully remove and serve warm or at room temperature.
