Preheat the oven to 190C/375F. In a large bowl, add the canned salmon, breadcrumbs, egg, feta cheese, parsley, garlic, lemon zest, chopped onion, baby tomatoes, paprika, salt and pepper.
Combine thoroughly using your hands or a fork until everything is well broken down and mixed together.
Tip: fry off a bit of the salmon mixture in a frying pan. Taste, and season accordingly based on your preference, before adding the salmon mixture to the loaf dish.
Get your loaf dish/tin and using a clean kitchen towel or pastry brush, rub a thin layer of room temperature butter around the inside of the tin. You can also use a butter wrapper from the fridge. Then place down some parchment paper so you can easily remove the salmon loaf once cooked.
Place the salmon mixture into the loaf and press down so the surface is even. Bake in the oven for 40 minutes, then remove and leave to cool in the dish/tin.
Meanwhile, make the yogurt lemon sauce by combining greek yogurt, lemon juice, chives, olive oil, salt, and pepper in a small bowl. Taste and season accordingly.
Once your salmon loaf has cooled down slightly, remove from the baking dish and serve up with the sauce. Enjoy with rice, potatoes, or bread.
