Avocado Tuna Salad

Name: Avocado Tuna Salad
Prep time: 5 min
Total time: 5 min
Yield: 2 servings
Cuisine: International
Ingredients: 1 tin tuna in water (about 145 g drained); 1 ripe avocado (about 200 g); 1 tablespoon lemon juice; 2 tablespoons finely chopped red onion; 1 celery stick, diced small; 2 tablespoons chopped parsley; ½ teaspoon fine salt; ¼ teaspoon black pepper; Optional: ¼ teaspoon chilli flakes

This is what to make when there is nothing in the house. Tinned tuna and a ripe avocado are both things you can keep on hand, and together they are a genuine meal.

Drain the tuna hard. That single step is the difference between a creamy salad and a wet one.

Ingredients

Instructions

1
Drain the tuna thoroughly, pressing the lid down firmly to squeeze out the liquid.
2
Mash the avocado in a bowl with the lemon juice, salt and pepper.
3
Flake in the tuna and fold, keeping some texture rather than mashing it smooth.
4
Stir through the onion, celery, parsley and chilli flakes if using.
5
Serve on toast, in lettuce cups, with crackers, or stuffed into a tomato.

Recipe tips

Tuna in water gives a cleaner result here. Tuna in oil works but you will need less avocado and more lemon.
Chill for ten minutes before eating if you have time — it firms up and tastes less flat.
For a keto lunch, serve in lettuce cups or a halved cucumber rather than on bread.
A teaspoon of capers or chopped gherkin lifts it noticeably.

Storage

Keeps one day in the fridge in a sealed container with film on the surface. Fish and avocado both deteriorate quickly, so do not push it further.

Frequently asked questions

Can I use tinned salmon instead?

Yes, and it works well. Drain it just as thoroughly and remove any bones and skin if you prefer.

Do I need mayonnaise as well?

No. A ripe avocado binds the tuna on its own. If yours is firm, add a spoon of curd rather than mayonnaise.

Is this suitable for a low-carb diet?

As written it is about 8 g of carbohydrate per serving, most of it fibre from the avocado. Served on bread, that changes.
