Place the cottage cheese into the bowl of a food processor. Blend until completely smooth.
In a small bowl, whisk the eggs, 1/4 cup of the whipped cottage cheese, salt, pepper and garlic powder.
Coat a large pan with nonstick cooking spray. Heat over medium-low heat. Cook the spinach until it wilts. Remove from pan.
Coat the pan with nonstick cooking spray again. Pour in the beaten egg mixture to coat the bottom of the pan. Allow the eggs to set and the edges to become firm. As the edges begin to set, gently lift them with a spatula and tilt the pan so uncooked egg runs underneath.
Arrange the spinach in half of the circle. Spread the remaining cottage cheese over the spinach.
Carefully fold the other half of the egg circle over the spinach and cottage cheese. Use a spatula to nudge the omelet out of the pan and onto a serving plate.
