Wash lettuce, pat dry and tear into bite-sized pieces. Place lettuce in large salad bowl, add dressing and toss. Sprinkle with Parmesan cheese and croutons and toss well. Arrange lettuce mixture on salad plates and top with fried oysters and anchovies.
Drain oysters and remove any remaining shell pieces. In small bowl or pie plate combine flour, bread or cracker crumbs, salt and pepper. In a heavy skillet heat ¼ inch oil until hot but not smoking. Add milk to oysters and stir. Individually, coat oysters with flour mixture and drop into hot oil. Fry for 2 to 3 minutes on each side or until browned. Place on absorbent paper to drain.
