Preheat oven to 375 °F. Spray a muffin tin with oil or non-stick spray.
Combine potato shreds with garlic powder, salt and pepper. Evenly distribute potato mixture in muffin tins and press the mixture in the middle using a spoon so that it forms a nest.
Bake 30-35 minutes or until its golden brown with crisp edges.
While nests are baking, combine eggs, onions, peppers, and salsa in a bowl.
When nests are golden brown, remove from oven and fill each one with ¼ cup of egg mixture. Top with cheese.
