Preparation
Step 1
Drain tuna and mash with mayonnaise, Dijon mustard, lemon zest and juice. Mix in red onion, capers or olives, marinated capsicum and artichoke, fresh capsicum and parsley. Season with salt and freshly cracked black pepper.
Step 2
Cut French bread baguette into two or three lengths and split in half. Spread each piece with butter. Spread with tuna mixture and top with sliced tomato and basil (if using).
If you like, you can top with a bit of shaved parmesan or grated cheese and grill for a few minutes until golden.
