Steps
- Heat 1 tablespoon of oil in a pan over medium-low heat. Add the leek, carrot, and celery, and cook for 10 minutes, stirring until softened. Incorporate the tomatoes, beans, and stock, then simmer over medium heat for 20 minutes until slightly reduced. Stir in the mustard.
- Preheat the oven to 200°C. Lightly grease 4 individual baking dishes or ramekins with oil.
- In a lightly oiled pan, sear the tuna loins for 1 minute on each side. Cut them into bite-sized pieces. Layer the beans, followed by the tuna, and then more beans in each dish.
- In a bowl, combine panko, garlic, parsley, and 1 tablespoon of oil. Sprinkle this mixture over the top of the layered ingredients. Bake for 20 minutes or until golden and bubbling. Serve with a salad.
