Preheat the air fryer to 200C (350F) for 5 minutes.
Meanwhile, cut chunks of the fish fillet, zucchini, and lemon.
Take a skewer and start and end with salmon. Thread salmon and fold veggies tightly on the skewer; try to make at least two skewers per person.
Take the air fryer basket and lay down 3 or 4 skewers.
Lower the temperature to 180C (300F) and cook the fish for no more than 10 minutes.
Meanwhile, make the sauce. Mix the yoghurt/or sour cream with finely chopped pickled cucumber; add 1 tbsp of ketchup, one minced clove of garlic and seasoning at taste.
Once ready, take out the skewers and enjoy.
Enjoy the dish while warm next to an aromatic white wine glass.
