Rub the hake fillets with olive oil, then season with garlic powder, fish spice and salt.
Cut the hake into roughly 2cm pieces, then give it a dusting of flour.
Heat a large pan over high heat. Add a little oil to the pan, then once the oil is hot, add the hake and fry for about 2 minutes a side.
Remove from pan and place on paper towel to get rid of the excess oil.
Heat a griddle pan over very high heat. Add the asparagus, season with salt and black pepper and fry until charred. Now repeat with the lettuce hearts and lemon wedges.
Place the asparagus together with the lettuce and the rest of the salad ingredients on a plate and add the hake. Drizzle with a little good quality Extra Virgin Olive Oil and garnish with fresh basil. Add a charred lemon wedge and serve.
