Place the cutlets, pounding them out thinly, taking care not to tear them. Salt and pepper on both sides.
On one half of each cutlet, place a slice of ham, a slice of cheese and ham again.
Fold and either tap the edges together firmly with a schnitzel mallet or secure with toothpicks.
Beat eggs in a soup plate. Now turn cutlets first in flour, pull through egg and roll in breadcrumbs.
Heat plenty of oil in a large frying pan (or 2 pans). Put in Cordon Bleus, fry until golden brown and drain on paper towels.
Serve garnished with lemon wedges.
