For the fried salmon fillet on leaf spinach, sprinkle the salmon fillet with lemon juice, salt and pepper.
Drizzle a heated pan with olive oil, quickly sear the salmon and finish frying in the oven at 150° for about 10 minutes.
Cook the spinach leaves with the crushed garlic in a saucepan for 10 minutes, salting and peppering to taste.
Remove the salmon from the oven, arrange it on a plate with the spinach and serve the roasted salmon fillet on leaf spinach immediately.
