With just four ingredients, it’s proof that simplicity can be seriously satisfying. Juicy tomatoes, salty tuna, and sharp red onion come together in perfect harmony—especially after a quick pickle to mellow the onion’s bite. Ideal for a hot day or when you’re after something fuss-free but full of flavour. Serve with wholegrain toast and some leafy greens to make it a more substantial meal.

Method

1

Gather and prepare your ingredients.

2

Place the red onion and red wine vinegar into a bowl and toss to coat. Set aside for 10 minutes to lessen the burn of the raw onion. If your onions are particularly strong you could rinse them under cold water first, or add a small pinch of white sugar.
