Ingredients

• 1 tin of tuna in its own juice

Method

You’ll need: chopping board · knife · mixing bowl · sieve

1. Drain the tuna well. Finely dice the red onion and celery and chop the dill.
2. Mix the tuna with the celery, red onion, dill, Dijon mustard and Greek yoghurt in a bowl. Season to taste with salt and black pepper.
3. Halve the Hass avocado, remove the stone and carefully scoop out a little of the flesh. Make sure the skin stays sturdy.
4. Lightly mash the scooped-out avocado and fold it into the tuna mixture. That makes the filling especially creamy.
5. Spoon the tuna cream into the avocado halves and press down gently. Finish with a little dill and black pepper if you like.
6. Serve fresh and enjoy the boats straight away.

Good to know

Swaps

Tuna in its own juice → tinned wild salmon (more omega-3, milder flavour) Greek yoghurt → coconut yoghurt without additives (creamy, dairy-free) Red onion → chives or spring onion (milder) Dijon mustard → freshly squeezed lemon juice with a little horseradish (fresher flavour)

Allergens

Contains fish, milk (Greek yoghurt), mustard and celery. Generally suitable for children; in pregnancy, keep the tinned tuna well chilled and limit tinned tuna, as the NHS advises.

Frequently asked questions

Does tinned tuna still contain omega-3?

Yes, tuna provides omega-3 fatty acids, although the amounts vary with species and processing. Oilier fish such as salmon or mackerel are usually higher, but tuna still contributes a solid amount.

What's in avocado nutritionally?

Avocado mainly contains monounsaturated fats, fibre, folate, potassium and vitamin E. That combination is exactly what makes it so interesting in low-carb dishes.

Can red onion cause problems?

It can, especially with a sensitive gut. Red onion contains fructans – fermentable carbohydrates that don't agree with everyone.

Does dill really matter nutritionally?

In the usual amounts, dill is more of a nice bonus than a big supplier of nutrients. It brings small amounts of essential oils and plant compounds.

Why is Greek yoghurt more than just creamy here?

Greek yoghurt provides protein and, depending on the product, calcium. At the same time, it softens the heat of the mustard and binds the filling without mayonnaise.
