Dredge the cutlets in the flour, then dip in the curdled soy milk and lemon juice/vinegar mixture. Mix the bread crumbs and soy parmesan in a flat soup dish or plate and coat the cutlets all over.
Heat the margarine in a large heavy non-stick frying pan over medium heat. Cook the cutlets until both sides are golden brown. Drain on paper and serve with lemon wedges to squeeze over.
