I've been making tuna melts since I was a teenager, and honestly, they never get old. There's something so satisfying about that combination of creamy tuna salad and melted cheese on toasted bread. The key is getting everything just right – not too much mayo in the tuna, the perfect amount of cheese, and timing that broiler so the top gets golden without burning. My version uses a mix of canned tuna (I prefer the kind packed in water) with just enough mayonnaise to bind it together. I add diced celery for crunch and a squeeze of fresh lemon juice to brighten everything up. Some people go heavy on the mayo, but I think that makes the whole thing soggy. You want the tuna mixture to hold together but not be swimming in dressing. The cheese situation is crucial here. I use a good sharp cheddar or Swiss – something that melts well but has enough flavor to stand up to the tuna. And here's my secret: I toast the bread first, then add the tuna, then the cheese. This prevents the bottom from getting soggy while the top is browning under the broiler. The whole thing takes maybe ten minutes from start to finish. These are perfect for a quick lunch or light dinner. I often serve them with some pickles and maybe a simple green salad. They're also great for using up that extra loaf of challah or rye bread that's starting to get a little stale.
