Heat about 2 inches of vegetable oil in a deep pan over medium heat.
Wrap each mozzarella stick with an egg roll wrapper, sealing the edges with beaten egg.
Mix breadcrumbs, garlic powder, Italian seasoning, salt, and pepper in a shallow bowl.
Dip each wrapped mozzarella stick into the breadcrumb mixture for extra crispiness.
Fry in batches until golden brown, about 2-3 minutes per side.
Remove from oil and drain on paper towels.
Serve hot with marinara sauce for dipping.
