Preheat oven to 425℉. Spray the sides & bottom of an 8x8 inch pan.
Add frozen potatoes into the bottom of the pan. Add raw peppers & onions on top of the potatoes.
In a medium bowl, add eggs, egg whites, cottage cheese, salt, garlic & onion powders and pepper. Use an immersion blender to blend. If you don't have an immersion blender, just use your regular blender. Pour egg mixture over the potatoes & peppers.
Sprinkle cheese over the top.
Bake uncovered for 45-50 minutes. The top will get brown, that's ok - we want the center cooked through. When the center is firm to the touch & the top is golden brown, it should be done.
