Cook lasagna and let it cool completely. Cut into small, 2-tablespoon sized pieces.

Lay out an egg roll wrapper. Place 2 tbsp lasagna filling and 2 tsp mozzarella cheese on one corner. Fold the wrapper like a burrito, tucking in the sides, then roll tightly to the end. Moisten the final corner with water to seal.

Lightly spray or brush the outside of each egg roll with oil for crispiness.

Arrange egg rolls in a single layer in your air fryer basket. Cook at 380°F (190°C) for 12-16 minutes, flipping halfway through, until golden brown and crispy.

Let the rolls cool slightly as the filling will be very hot. Serve immediately with your favorite dipping sauce.
