The baguette transforms this easy sandwich into something special: crisp on the outside, soft on the inside, and sturdy enough to hold layers of melty cheese, smoky ham, and a generous dose of jam. The jam adds a burst of sweetness that pairs perfectly with the savory, slightly salty ham. This version is endlessly adaptable; swap the cheese, try different jams, or even toast the baguette halves for an extra crunch. It’s a quick fix that feels a little indulgent and completely satisfying.
