A Tuna Mayo Sandwich is usually made with tuna, mayonnaise and bread. Common additions include lettuce, cucumber, sweetcorn, onion or lemon juice; draining the tuna well helps keep the filling from making the bread soggy.
Drain and flake the tuna, then mix it with mayonnaise and spread it between slices of bread. Add crisp vegetables if you like, and assemble the sandwich close to serving time for the best texture.
A Tuna Mayo Sandwich can be a convenient source of protein, while mayonnaise and the choice of bread shape the overall meal. Adding lettuce, tomato or other vegetables is an easy way to make the filling more varied.
A Tuna Mayo Sandwich is best eaten within a day when kept covered in the refrigerator. Keep it chilled rather than leaving it out, particularly in warm weather, and discard it if it has been sitting at room temperature for hours.
Freezing a Tuna Mayo Sandwich is not recommended. Mayonnaise can separate as it thaws, and the tuna filling and bread may become watery or soft; make the sandwich fresh instead.
A Tuna Mayo Sandwich goes soggy when excess liquid from the tuna or other ingredients seeps into the bread. Drain the tuna thoroughly, pat wet vegetables dry, and assemble the sandwich shortly before eating.
Sturdy sliced bread, a roll or a baguette all work well for a Tuna Mayo Sandwich. Choose soft bread for an easy-to-eat lunch, or a firmer loaf if you want it to hold a moist filling without collapsing.
Yes, you can make a Tuna Mayo Sandwich without mayonnaise by mixing the drained tuna with plain yogurt, mashed avocado or a little olive oil. The texture and flavor will differ, so add the alternative gradually until the filling holds together.
A Tuna Mayo Sandwich pairs well with a side salad, crunchy vegetables, soup or pickles. For a lighter lunch, serve it with fresh vegetables; for a more substantial meal, add a bowl of soup.
Yes, a Tuna Mayo Sandwich can be packed for lunch if it stays cold until you eat it. Use an insulated lunch bag with a cold pack, and keep the sandwich separate from warm items.

A tuna mayo sandwich is made with tuna mixed with mayonnaise and tucked between slices of bread, sometimes with lettuce, sweetcorn or a little seasoning. It is a familiar café and packed-lunch choice in Britain, and is also an easy lunch across many English-speaking countries. The filling is creamy and savoury, with a soft texture that contrasts with fresh, crisp additions. It is usually served cold, on its own or alongside a simple salad or a bowl of soup.
The bread provides much of the carbohydrate, while tuna contributes protein; there are 11 g of protein per 100 g. For a lighter sandwich, use less mayonnaise and add extra salad leaves or sliced vegetables.
