01 - Preheat oven to 350°F for finishing the fish if desired.
02 - Pat hake fillets dry with paper towels and season both sides with sea salt and black pepper.
03 - Heat 2 tablespoons olive oil in a large non-stick skillet over medium-high heat. Place fillets skin-side down, press gently with a spatula for 1 minute to promote crispiness.
04 - Sear skin side for 3 to 4 minutes until golden and crisp. Flip and cook for 2 to 3 minutes until just cooked through. For thicker fillets, transfer to the oven and cook 3 to 4 minutes more. Rest fillets skin side up.
05 - In a separate skillet, heat 2 tablespoons extra virgin olive oil over medium heat. Add ground beef and cook, breaking up with a spoon, for about 5 minutes until browned and slightly crisp.
06 - Stir in smoked paprika, sweet paprika, cumin, oregano, garlic powder, cayenne pepper, and sea salt. Cook for 1 minute until fragrant.
07 - Mix in tomato paste and red wine vinegar; cook for 1 to 2 minutes to blend flavors.
08 - Add gluten-free breadcrumbs and stir well. Cook for an additional 2 to 3 minutes until the mixture becomes crisp and crumbly. Adjust seasoning to taste.
09 - Place chorizo-style beef crumb on warmed plates, top with crispy hake fillets skin side up, and garnish with chopped parsley and lemon wedges.
