Heat a large fry pan with a medium heat and add in the olive oil

While the oil is heating, thinly slice the onions in julienne style (watch video to see the technique), thinly slice the cloves of garlic

Add the sliced onion and garlic into the hot fry pan, mix together, then mix every 1 to 2 minutes so everything evenly sautes

In the meantime, add the cod fillets over some paper towels and pat completely dry, then season with sea salt & black pepper and cut each fillet into 4 evenly sized pieces, for a total of 12 pices of cod

After cooking the garlic and onions for 10 to 15 minutes and they're lightly browned, add in the sherry vinegar, paprika, oregano and season with sea salt & black pepper, mix together, then add in the white wine and bay leaves, mix and then simmer

After 3 to 4 minutes and the alcohol has been cooked off in the wine, add the pieces of cod, all in a single layer and evenly spaced out, then gently flip each piece that way all the fish is absorbing all the flavors in the pan, then place a lid on the pan and lower to a low-medium heat

Once the pieces of cod are cooked through, about 4 minutes, remove from the heat, serve directly our of the pan sprinkled with fresh parsley, enjoy!
