Variations

• Cheese addition: Add slices of Swiss, provolone, or sharp cheddar for a richer sandwich.
• Spicy kick: Use horseradish sauce or a spicy mustard instead of Dijon.
• Greens swap: Substitute arugula or baby spinach for romaine lettuce.
• Vegetable upgrade: Add thin cucumber slices, red onion, or pickles for extra crunch.
• Toasted version: Toast the baguette lightly before assembling for added texture and warmth.

Storage/Reheating

This sandwich is best enjoyed fresh. If preparing in advance, assemble without the tomato or condiments to prevent sogginess. Wrap tightly in parchment or foil and refrigerate for up to 24 hours. Avoid reheating, as the sandwich is designed to be eaten cold or at room temperature.
