A starter material isn't technically necessary, though a good amount of some sort of neutral, non-food based material (such as leaves, dirt, etc) will help to keep it from smelling like rotten food. I agree that adding worms is an unrelated question. Otherwise, the natural flora and fauna will breakdown the foods over time, as long as a reasonable nitrogen ratio is maintained.
