In a large skillet or frying pan, heat 2-4 tablespoons of oil (light olive oil is my fave) over medium-high heat. Once the oil is hot, carefully place the breaded pieces of fish into the hot oil. Cook the fish for about 3-4 minutes on each side, or until golden brown and crispy. Depending on the thickness of the fillets, cooking time may vary. Transfer the cooked fish to a paper towel-lined tray to drain any excess oil.
