Step 1

Drain the oil from 1 tin of sardines into a small bowl and set aside. Drain the oil from the other tin into another small bowl and whisk in 1 tablespoon of parsley, vinegar, lemon zest, and black pepper, to taste. Add the sardines, stir to combine and set aside for up to 1 hour.

Step 2

After 45 minutes, put a rack 3-inches from the broiler and heat the oven to the broiler setting on high. Brush each slice of bread on 1 side with the reserved oil. Put the bread, oil side up, onto a cooling rack set inside a half sheet pan and broil 2 to 3 minutes or until golden brown and crisp.

Step 3

Halve the avocado and remove the pit. Smash the flesh in each half with a fork.

Step 4

Spread the avocado evenly onto the toasted bread. Top evenly with the sardines. Pour any remaining dressing on top and garnish with the remaining parsley.

Step 5

Season lightly with sea salt and serve with lemon wedges.
