- Pat fish dry.  Combine flour, salt, and pepper in a shallow bowl and place each piece of fish into the flour. Turn to coat and then shake off any excess. 
- Heat olive oil and 1 tablespoon of butter in a non stick pan over medium-high heat and cook the fish in batches for 4-5 minutes per side or until golden brown and cooked through. Remove the fish from the skillet onto a plate. 
- If there’s too much oil in the pan, discard most of it. Return the pan to heat, melt one tablespoon of butter, add the garlic and cook for 30 seconds. 
- Add wine (or chicken stock) to the skillet and cook until it reduces in half. Add lemon juice, and the remaining butter and cook gently until the sauce emulsifies. 
- Add in the capers, lemon zest, and chopped parsley and stir before removing from the heat. 
- Spoon the sauce over the fish and serve warm with mashed potatoes and vegetables or salad.
