STEP BY STEP

Let’s make it.

Drain the tuna thoroughly and weigh the drained fish. Wash and dry the lettuce leaves.
Whisk the yogurt with the lemon juice, mustard, parsley and pepper in a large bowl.
Fold in the tuna and cucumber, keeping some of the tuna in larger flakes.
Add the avocado and fold gently so it keeps its shape. Divide the lettuce among the serving plates.
Spoon the filling into the leaves to make 4 servings. Serve promptly while the lettuce is crisp.
