Ingredients

• ·1 × 140g can wild-caught tuna in olive oil or water, drained
• ·1 ripe avocado
• ·1 tbsp capers, roughly chopped
• ·¼ small red onion, very finely diced
• ·Juice of ½ lemon
• ·Sea salt and black pepper
• ·Pinch of red pepper flakes
• ·4–6 large romaine or butter lettuce leaves
• ·Fresh dill or flat-leaf parsley, to garnish (optional)

Instructions

1. 1 In a medium bowl, mash the avocado with a fork — leave it slightly chunky, not completely smooth.
2. 2 Add the drained tuna, capers, and red onion. Mix gently to combine without breaking up the tuna too much.
3. 3 Season with lemon juice, salt, pepper, and red pepper flakes. Taste and adjust.
4. 4 Spoon the tuna-avocado mixture into the lettuce cups, dividing evenly.
5. 5 Garnish with fresh dill or parsley if using, and serve immediately.
