Place the cottage cheese into a microwave-safe bowl and stir in the garlic powder and dried oregano.
Spread the marinara sauce in an even layer over the cottage cheese base.
Distribute the shredded mozzarella cheese evenly across the top of the sauce.
Arrange the turkey pepperoni slices in a single layer over the mozzarella.
Microwave on high power for 90 seconds or until the mozzarella is fully melted and the cottage cheese is warmed through.
Remove from the microwave and garnish with grated Parmesan cheese.
Allow the bowl to rest for 60 seconds to set the texture before consuming.
