Thaw K&N's Mortadella Slices as per instructions given on the pack.
Whisk 6 eggs in a bowl and add onion, carrots, milk, salt, black pepper and whisk again to combine.
In a separate, pan heat oil and add half of the egg mixture to fry.
As the mixture fries, set on it 4 half folded Mortadella Slices, as pairs in a row and top with coriander leaf stalks.
Fold the egg over Mortadella Slices to form a roll and dish out.
Repeat with remaining half of the egg mixture.
Cut the rolls in 4 pieces and serve hot.
