Soak rolls in cold water. Peel and finely chop the onion. Squeeze the bread roll well and knead it with minced meat, onion, egg, some salt, pepper and sweet paprika in a mixing bowl.
Cut the mince into eighths and form each portion into a flat minced steak. Cut ham and cheese slices in half. Cover 4 minced steaks with ham and cheese so that one minced edge remains free. Cover with the remaining 4 steaks and press the edges well together.
Heat the oil in a frying pan and fry the minced cordon bleus over medium heat for 6-8 minutes while turning. Put the noodles in plenty of boiling salted water and cook according to the instructions on the packet. Put the buttered vegetables unfrozen in a hot pan with a little water.
Steam for about 8 minutes and stir from time to time. When the water has evaporated, the vegetables are ready. Drain the noodles on a sieve and rinse briefly under cold water. Melt butter in a hot pot and toss the noodles in it.
Arrange noodles, vegetables and chopped cordon bleus on a plate. Sprinkle with chopped parsley as desired and garnish with parsley leaves.
