Chocolate chip ice milk

I find this more refreshing than the heavy cream and custard types, because it melts away so quickly and leaves a moist aftertaste instead of a creamy one.

1 cup half and half
2 cups 2% milk
1/2 cup sugar
vanilla to taste

Stir to combine, churn per ice cream machine's manufacturer's instructions, adding 1/2 of a Hershey's bar, chopped, during the last five minutes of processing.
