In a small bowl, mix together the Parmesan cheese and lemon juice. Season with dried basil and pepper or spices which you prefer. Mix well and set aside.
Flip the fillets over and broil for a couple more minutes. Remove the fillets from the oven and cover them with the Parmesan cheese mixture on the top side. Broil for 2 more minutes or until the topping is browned and fish flakes easily with a fork. Be careful not to over cook the fish.
