Tunisian casse-croute (a portable food snack) is bread stuffed with a crunchy, juicy salad of tomato, cucumber, capsicum and hard-boiled egg, spiced up with harissa. To make it office-friendly, pack the salad in a jar and assemble it when you're ready to eat. Other options include capers, boiled potato, parsley, coriander, anchovies, capers or pickled chillies. Or swap out the tuna for left-over pan-fried king salmon, roast chook or mozzarella.
½ red onion, finely sliced
2 tbsp red wine vinegar
2 tbsp olive oil
100g sustainably fished canned tuna in oil, drained
1 tomato, diced
½ small cucumber, halved and finely sliced
½ red capsicum, diced
1 tbsp olives, pitted
1 spring onion, finely chopped
1 hard-boiled egg, cut into 6 wedges
2 rolls, cut from a rustic baguette
1 tsp harissa paste
2 tbsp tomato passata
1 tbsp olive oil
1. Toss the red onion in vinegar and leave for 30 mins. To make the relish, mix harissa paste, tomato passata and olive oil until smooth.
2. To make the salad, whisk the olive oil, onions and vinegar, sea salt and pepper in a bowl. Add the tuna, tomato, cucumber, capsicum, olives and spring onions, tossing well.
3. Split the rolls and spread the base with hummus and the top with harissa relish.
4. When you're ready to eat, spoon the salad and hard-boiled egg onto the base, being generous with the juices. Add the top, press down firmly and leave for 10 minutes to soften before eating.
