In a shallow pan place salmon then add onion rings, bayleaf, peppercorns, salt and just enough water to cover the fish. Boil then simmer for 5 minutes. Drain and cool the salmon. Cut beef into 4 serving pieces then pound to flatten. Place in an ovenproof dish and lay salmon on top. Combine crumbs, parsley, garlic and one half the melted butter. Season with lemon juice to taste. Cover the steaks with the crumb mixture then top with the ham and shrimp. Pour the remaining butter on top. Bake at 400/F for 15 minutes or until steak is done.
