First, mix the flour, salt and black pepper.
Heat the butter in a large frying pan over medium-high heat.
When the butter is hot, add the fish fillets. Cook for 3 minutes.
Flip the fillets over and fry for 1 more minute. Remove the fish and set it aside.
When all of the fish is cooked, place each fillet on a separate plate and serve.
Using the same frying pan, add some more butter and a little milk.
When the butter is hot, add the lemon juice and parsley to the melted butter. Stir constantly until the sauce thickens slightly.
Drizzle the lemon butter sauce over the fried sole fillets. Garnish with fresh parsley.
Serving Suggestions: This dish may be served with rice or potatoes. One may also use vegetables along with the fish.
