Ingredients

• 1 large ripe avocado
• 1 tin (3.75 oz / 106g) sardines in olive oil or water, drained

• 1 tbsp (15 ml) fresh lemon juice

• ¼ tsp (1.5g) salt, or to taste
• Freshly ground black pepper, to taste

Instructions

1. Prepare the Avocado: Slice the avocado in half lengthwise and remove the pit. Carefully scoop out about half of the flesh from each side, leaving a sturdy shell. Place the scooped-out flesh into a medium mixing bowl.
2. Combine : To the bowl with the avocado flesh, add the drained sardines, finely sliced spring onion, paleo mayonnaise, fresh lemon juice, ground turmeric, and salt.
3. Mix and Mash: Using a fork, mash all the together until they are well combined. You can leave it chunky for more texture or mash until it’s smooth and creamy.
4. Stuff and Serve: Taste the mixture and adjust seasoning if needed. Spoon the sardine filling evenly back into the hollowed-out avocado shells. Garnish with extra spring onion or a sprinkle of paprika and serve immediately.

Pro Tips

• Not a fan of sardines? Canned tuna or salmon (wild-caught, if possible) work wonderfully as a substitute in this recipe.
• For an extra crunch and a pop of freshness, mix in a tablespoon of finely diced celery, red onion, or fresh cilantro.
• If you’re not serving immediately, press a piece of plastic wrap directly onto the surface of the filling to prevent browning.
