Blend eggs, cottage cheese, garlic powder, onion powder, black pepper and salt in a blender or with an immersion blender.
Pour egg mixture into a greased or parchment lined 9x13 baking pan. Stir in cooked ground sausage, chopped spinach and cherry tomatoes. Stir until the mix ins are evenly spread throughout the pan.
