A tuna sandwich can fill the gap any time - lunch box, tea time, party time - any occasion.

One tin of tuna will make sandwiches for four people - four rounds of two slices of bread.

Butter your bread and put a layer of finely sliced cucumber on the bottom slice.

Top with the tuna mixture and put the second slice on top to make a sandwich.

Cut the sandwich into four - I like triangles, some people like squares - it's a matter of choice.

You can see the lovely juicy tuna oozing out of the sandwich here!

Make sure that you have some paper towel nearby so that people can mop their hands - seafood sandwiches are often messy because mayonnaise is used quite a lot to bind the fillings.

Cook's Notes

Variations for your tuna sandwich:

  • Cooked sweetcorn, either out of a tin, fresh or defrosted from the freezer is a great choice to mix into your tuna and mayonnaise mixture. 
  • Try diced onion mixed in - about a half a medium onion for one can of tuna will be the right mixture. Put a layer of washed and dried salad leaves on top. 
  • I frequently dice my cucumber and mix through evenly before I spread it on the bread. 
  • Diced tomato is another good addition to the tuna mayonnaise mixture - or a combination of cucumber and tomato makes it really succulent. 


Whilst fresh tuna is classed as an oily fish and so counts as an oily fish serving, canned tuna isn't. The canning process destroys the oils in the tuna - here's a pubMed article about tuna fish and the various cooking methods, explaining their findings into how much of the healthy oils are lost during the canning process. 

However, canned tuna is full of protein and it's extremely tasty - it's also one of the fish that people who say 'I don't really like fish' will eat.  It has no bones, it's meaty in texture and will go into many different dishes.
