Breakfast panna cotta

1. To make the dressing, mix the yoghurt and mayonnaise. In a blender, blend the herbs, spring onion, olive oil and lime juice until smooth and season. Fold the yoghurt and herb mixtures together and store in an airtight container.
2. To make the tuna, season the fish and drizzle with olive oil. Cook to your preference.
3. To assemble, toss the baby marrow ribbons, rocket, parsley, preserved lemon, Parmesan, cannellini beans, spring onion, pistachios, lemon vinaigrette, salt and pepper.
4. Spoon the dressing into the base of a large salad bowl, then top with the dressed salad. Place the remainder of the dressing in small sauce bowls to serve on the side.
5. Cut the tuna into 6 slices and place to the side of the salad, then place the gem lettuce to the side. Drizzle everything with olive oil and garnish with the dill and lemon wedges.
