Justine Schofield's Beef Asada with Pico De Gallo

I used to make this beef asada with tortillas, but one time I didn't have any in the pantry, so I served it with a cabbage salad and it was a revelation. It's beautifully filling and fresh topped with a classic pico de gallo. Don't skip grilling the spring onions for this. They become caramelised, smoky and sweet and really transform the flavours. It's a great one for spring barbecues.
