01 - Pat hake fillets dry with paper towels and season both sides with salt and pepper.
02 - Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat. Place fillets skin side down and press gently for 1 minute to achieve crispiness.
03 - Cook skin side for 3 to 4 minutes until golden and crisp. Flip and cook the other side for 2 to 3 minutes until just cooked through. For thicker fillets, transfer to a 350°F oven for 3 to 4 minutes to finish cooking. Remove and rest skin side up.
04 - In a separate skillet, heat 2 tbsp extra virgin olive oil over medium heat. Add ground beef and cook, breaking up with a spoon, until browned and slightly crisp, about 5 minutes.
05 - Stir in smoked paprika, sweet paprika, cumin, oregano, garlic powder, cayenne pepper (if using), and salt. Cook for 1 minute until fragrant.
06 - Add tomato paste and red wine vinegar, cooking for an additional 1 to 2 minutes.
07 - Add gluten-free breadcrumbs, stirring well, and cook for 2 to 3 minutes until mixture is crisp and crumbly. Adjust seasoning to taste.
08 - Spoon the beef crumb onto warm plates. Place a crispy hake fillet on top, skin side up. Garnish with chopped parsley and lemon wedges.
