Pan-Fry:
Dip fillets in one beaten egg. Coat fillets lightly with fine breadcrumbs (resulting in darker coloured fillets) or flour. Season with salt and pepper. Fry in 2 tbsp. oil or butter for 6-7 minutes, turning twice. (Do skin side first and last for crispy texture.)

Bake in Foil:
Brush foil with 1 tbsp. oil or melted butter. Place fillets on foil and sprinkle with 1 tbsp. lemon juice. Season with salt and pepper. Seal and bake 5-6 minutes at 450°F (230°C).
