French fries with fish?  Unless you're in England thats blasphemy.  For Crappie fillets the proper side is home fries.  I usually do my fish fried, but once in a while I like something a little lighter so I will throw some fillets in a foil pack with a bunch of butter, some diced green peppers, onions, and jalapenos, bit of salt and pepper, and maybe even a couple shakes of Parmesan or hot sauce.  Throw em in the oven at 350 for 15 minutes or so and they're good to go.
