Tuna sandwiches are a swift, budget-friendly and protein-rich meal savoured by many throughout the UK. While the traditional recipe is difficult to surpass, experts suggest adding one straightforward addition to the mayonnaise to make it considerably healthier.
Expert Tip for Better Tuna Sandwiches
Expert cook Alyssa Brantley from food website Everyday Maven revealed: "You'll love how simple it is to mix up and the fun twist it takes on a classic favourite even more."
"You might as well just grab your ingredients now because I'm sure you're already craving some, just like I am right now."
The twist in question: vegetables. By incorporating carrots, celery, onion, and more, the tuna filling gains a fresher flavour and a crunchier texture that pairs beautifully with the tuna.
Why Vegetables Work
Alyssa continued: "I've been making this recipe for years as it was the most popular item on my small catering business menu back in grad school, and it still holds up as the best tuna salad I've ever eaten."
This tuna filling takes 30 minutes to prepare and serves up to eight people. You can also swap bread for lettuce wraps, salads, or serve it atop an avocado.

Ingredients for the Best Tuna Filling
- Four cans of tuna
- A 1/2 cup of chopped carrots
- A 1/2 cup of chopped celery
- A 1/2 cup of chopped parsley
- A 1/3 cup of chopped red onion
- Four medium scallions chopped
- One clove of garlic
- 10 tablespoons of mayonnaise
- One teaspoon of salt
- A 1/4 teaspoon of freshly ground black pepper
Method
Begin by opening your tuna cans and thoroughly draining the water. Empty the tuna into a large mixing bowl and set it aside.
Next, utilise a food processor fitted with the chopping blade to blitz your carrot, celery, parsley, red onion and scallion. Be sure to measure after chopping to ensure you have the correct quantity of each ingredient.
Should you not own a food processor, simply chop the ingredients very finely or use a cheese grater for a more refined result.
For the following step, transfer your ingredients into a bowl with the tuna, along with a small clove of crushed garlic.
Then incorporate the mayonnaise, salt and pepper. Use a fork to gently break up any particularly large chunks of tuna, then thoroughly combine all the ingredients. Adjust the seasoning as required.
