Tunisian Tuna and Harissa Sandwiches

Slice the baguette lengthwise, but not all the way through, creating a pocket for the filling. Lightly toast the baguette if desired for extra crispness.

In a small bowl, flake the drained tuna with a fork. Stir in the harissa paste until well combined.

Spread the harissa tuna mixture evenly inside the baguette.

Layer the halved Kalamata olives, chopped fresh parsley, thinly sliced cucumber, and thinly sliced red onion over the tuna.

Gently press the sandwich together and slice into two equal portions. Serve immediately.
