Of all the diner-inspired dishes, perhaps none sparks more debate than the humble tuna sandwich. Served hot or cold, it has ...

Top tuna with cheese, packing it on generously, and slide sandwiches under broiler. Broil until cheese melts and bubbles, 4-5 minutes. Remove tuna melts from broiler and serve immediately.

There's nothing better than a warm, cheesy tuna melt. For the ultimate gooey goodness, try one of these cheeses on your next toasted tuna sandwich.

This classic tuna melt can be made in a frying pan! If you like a little more texture to your toastie, it also works well with a tablespoon of finely diced celery folded through the filling.
