Ingredients
Cooking Instructions
- Wash the lettuce and tomato thoroughly, then dry them with paper towels.
- Slice the tomato into even rounds, approximately 1/4 inch thick.
- Peel the red onion and slice it as thinly as possible.
- Place the bread slices on a clean cutting board.
- Spread mayonnaise evenly over one side of each bread slice. Add a thin layer of Dijon mustard if desired.
- Arrange the white cheese slices over two pieces of bread, covering most of the surface.
- Layer the tomato slices over the cheese and season lightly with black pepper and salt if needed.
- Add the thinly sliced red onion, distributing it evenly so its flavor does not overwhelm the other ingredients.
- Place the lettuce leaves over the vegetables and finish with a few drops of olive oil if desired.
- Close the sandwiches with the remaining bread slices, press gently, cut diagonally, and serve immediately.

Notes
Cheese selection: Fresh mozzarella creates a soft, delicate sandwich, while white cheddar provides a firmer texture and sharper flavor. If using mozzarella, drain it well before assembling.
Prevent soggy bread: Pat the tomato slices dry with paper towels before adding them. This is especially important when preparing sandwiches for later.
Reduce onion sharpness: Soak sliced red onion in cold water for 5-10 minutes, then drain and dry thoroughly before assembling.
Keep the lettuce crisp: Dry the leaves completely after washing. Excess moisture can soften the bread.
Make-ahead preparation: Slice the vegetables and cheese in advance, but assemble the sandwiches shortly before eating. Keep perishable ingredients refrigerated.
Bread options: Soft white bread gives a classic deli-style texture, while sourdough or ciabatta provides a firmer bite that holds up better to juicy tomatoes.
