If you grew up in the ’70s and ’80s, you know that canned tuna used to be the butt of jokes. It has a reputation for being a cheap source of protein that tastes and smells, well, like cat food. Tuna sandwiches were included in many school lunches — and not many people liked them. But that was then.

Instructions
Preheat the oven to 400°F (200°C). Chop onion, bell pepper and celery finely and fry in butter in a large frying pan until slightly soft. Season with salt and pepper.
Mix tuna, mayonnaise, parmesan cheese and chili flakes in a greased baking dish. Add fried vegetables and stir.
Bake for 15-20 minutes or until golden brown.
Serve with baby spinach and olive oil.
Tip!
Canned tuna is a life-saver when fridge and freezer are empty. Try to choose high-quality, MSC-labeled tunafish—preferably in olive oil instead of sunflower oil.
In a small bowl, mix tuna, egg, vinaigrette and, if desired, mustard. Place buns on an ungreased baking sheet, cut side up. Broil 4-6 in. from heat 1-2 minutes or until golden brown.
Spread tuna mixture over buns; top with tomato and cheese. Broil 2-3 minutes longer or until cheese is melted.
