- Lettuce or spinach (optional)

Instructions

Tips for the Perfect Tuna Sandwich
Choose good tuna: Opt for tuna in water for a lighter option or in oil for a richer flavor.
- Handle the onion carefully: If raw onion is too strong for you, soak it in cold water for a few minutes before mixing to mellow its flavor.
- Mayonnaise variations: Try garlic mayonnaise, mustard, or Greek yogurt for different flavors.
- Bread choice: Pick a bread that can hold moisture well, such as sandwich bread, whole wheat, baguette, or pita.
