01 - Preheat oven to 350°F. Grease a 12-cup muffin tin with non-stick spray or line with silicone muffin liners.
02 - Combine eggs, cottage cheese, milk, salt, pepper, and garlic powder in a blender. Blend until completely smooth and frothy.
03 - In a mixing bowl, toss together spinach, red bell pepper, green onions, and shredded cheddar cheese until evenly distributed.
04 - Pour the blended egg mixture over the vegetables and cheese. Gently fold together until just combined.
05 - Divide the mixture evenly among the 12 muffin cups, filling each about 3/4 full to allow for rising.
06 - Bake for 18 to 22 minutes until the bites are set in the center and lightly golden on top.
07 - Let cool in the pan for 5 minutes. Run a knife around the edges of each cup to release, then remove carefully.
