Crunchy Oven-Fried Catfish - Kidney-Friendly Recipes - from DaVita.com K's note: we liked this, but thought it needed salt and twice as much Cajun mix. My hubby is okay with his sodium, so next time I'll add some salt to the Cajun cornmeal part of the recipe. Good news is that he likes it enough for another go-around, and it's crispy without traditional bread crumbs or grease.
