Cut chicken breasts in half. Skin and debone, then pound until flat. On each chicken breast, add 1 slice each of ham, mozzarella cheese and tomato and season with garlic salt, then roll the chicken breasts into rolls and secure with picks. Once this is done, then roll the chicken breasts in a mixture of bread crumbs, Parmesan cheese and parsley. Dip each chicken breast into butter and then into the bread crumb mixture again. Place chicken into a pan and bake, covered, at 350° for 35 minutes. Uncover and bake an additional 15 minutes.
