Place the flour in a large, shallow dish and dredge the fish in flour on both sides.
Heat the oil in a non-stick pan over medium-high heat.
Add the fish to the pan and season lightly with salt and black pepper. Reduce the heat to medium and fry for 3 minutes.
Flip the fish, season again lightly with salt and pepper, and drizzle ¾ tsp lemon juice over each fillet.
Fry for an additional 3 minutes.
Serving: Garnish with sprigs of parsley and lemon wedges.
