Combine tuna, egg, bread crumbs, onion, celery, capsicum, mayonnaise, sweet chilli sauce, hot chilli sauce, dill, salt, pepper and Worcestershire sauce. Mix well. Shape into 4 patties. The mixture will be very soft and delicate. Refrigerate for 30 minutes to make the patties easier to handle.
Coat a non-stick frypan with cooking spray or olive oil and fry the tuna patties for about 3 to 4 minutes per side, or until cooked through. These are fragile, so be careful when turning them.
