These healthy fish tacos can be made with cod or any other firm white fish. A lively kiwi salsa and red cabbage brighten up the colors and flavors of the crispy tacos and complete this easy dinner recipe. The key to perfectly golden, crunchy fish is patience--let your oil get nice and hot before you add in the battered pieces. Dip an instant-read thermometer into the oil to make sure it's up to temp before you get cooking.
