Method

1
Before cooking, allow the steaks to come to room temperature.
2
Firstly, make the caramelised red onions, heat the oil in a heavy-bottomed frying pan over a high heat. Add the onions, salt & pepper and let sauté over a lower heat for 15-20 minutes stirring occasionally to prevent sticking until they become soft and a golden colour.
3
Add the sugar and vinegar and turn the heat up to medium to dissolve the sugar and reduce the vinegar until the mixture is sticky and like a jam.
4
Season the steaks well with salt and pepper.
5
Place a frying pan with the oil on a high heat until smoking hot. Add the steaks and cook to preference (2-4 minutes per side). Slice the steak and leave to rest.
6
Slice the blaas in half to make a bun and add spread with mayo on both sides. Assemble the steak, caramelised onion, blue cheese and rocket. Add the bun lid on top to sandwich the filling together & serve.
