Quick steak fajitas with pickled red onions

Step 1

Slice 1 red onion thinly and put in a shallow glass/ceramic bowl with the juice from the 2 limes, sugar and plenty of salt. Toss and chill for 15 minutes.

Step 2

Meanwhile, slice the other red onion and the peppers, heat a drizzle of oil in a large pan and fry over a high heat for 5 minutes, stirring, or until golden but still crunchy. Add the Cajun seasoning and cook over a low heat until fragrant. Tip into a bowl; cover with foil.

Step 3

Heat another drizzle of oil in the pan, season the steaks and fry on a high heat for 2 minutes on each side for medium rare (or longer). Rest on a plate.

Step 4

Squeeze the juice from the pickled onion and put in a bowl. Slice the steaks and toss with the warm onion and peppers, and the resting juices. Serve in tortillas, with extras of your choice (see our suggestions).
