Marinate the steak in a few tablespoons of the BBQ sauce in a bowl.
Cling film the bowl and leave the steak to marinade on the fridge for at least an hour
Meanwhile, make the spring onion salad.
Thinly slice the spring onions and add the seasoning. Mix well.
Remove the steak at least 10 minutes before cooking
Heat a frying pan on a high heat. Add a bit of cold pressed rapeseed oil to the pan.
Cook each side of the steak on the hot pan to the doneness you want. I like it a bit pink in the middle.
Reduce the marinade to use as a sauce. Adjust seasoning to your own liking.
Slice the steak into thin strips across the grain.
Serve all the elements separately for everyone to assemble themselves.
Get a lettuce leaf and fill generously with steak, a bit of the marinade and top with some of the spring onion salad.
