1. Toss the breadcrumbs, Cajun seasoning, and salt together in a bowl.
Using a separate bowl, beat the eggs with the buttermilk.
Toss the fish with the flour, shake off the excess, and dip into the egg.
Shake off any excess egg, and press into the breadcrumb mixture.
2. Heat about 1/8 inch of oil in a heavy bottomed skillet over medium-high heat.
Cook for 3-5 minutes per side until the fish flakes easily and is nicely browned.
