There is nothing quite like a classic, diner-style Tuna Melt to hit the ultimate comfort food sweet spot. This recipe delivers the perfect contrast of textures: crispy, buttery grilled bread on the outside, and a creamy, crunchy tuna salad with melted, gooey cheese and juicy tomatoes on the inside. It is a nostalgic, quick-fix lunch or dinner that elevates a humble can of pantry tuna into a total masterpiece.
