Something magical happens when you top food with mayonnaise and cheese and then bake it. It forms this amazingly crisp but still creamy crust. If you’ve got any Slavic blood in you, you’re very familiar with this combination. I am a huge fan of seafood and it’s a very common dish on our dinner table. This is a winner on many counts – it comes together relatively quickly, looks impressive and is absolutely, lip smackingly delicious. As you take a bite of the juicy, flaky salmon with the tender onions and creamy and crisp crust, don’t be surprised if you find yourself closing your eyes with pleasure. Seriously delicious. Add a layer of sweet and juicy tomatoes and a smattering of fresh herbs to elevate the salmon to an even higher level of perfection.
