Ingredients
Method
1.Cook bread and frozen chips as packet directs. Make bearnaise sauce as packet directs.
2.Meanwhile, heat half of the oil in a large frying pan over high heat. Add onion. Cook, stirring, 7-8 minutes or until golden brown. Transfer to a heatproof bowl.
3.Heat remaining oil in pan. Add beef. Cook 1-2 minutes for medium, or until cooked to your liking. Cover with foil. Rest 1 minute.
4.Cut bread in half horizontally. Top with rocket, beef, beetroot, tomato, onion and half of the bearnaise sauce. Cut in half. Serve with chips and remaining sauce.
Par-baked ciabatta bread is sold at most major supermarkets. If unavailable, use individual rolls or thick bread slices. If bearnaise sauce is unavailable, use hollandaise sauce instead, adding a small handful of chopped herbs.
