1 bunch of parsley, finely chopped, stems removed (about ½ cup)
Method:
Generously season the steak with salt and pepper. Heat a frying pan over medium-high heat. Cook the steaks for 5 minutes, flip and cook for a further 4 minutes, or until the centre reaches 52°C for medium-rare (or cook to your liking). Remove from the pan and rest for 5-10 minutes, then slice.
While the steak is cooking, add olive oil to a frying pan over medium-high heat along with the corn cobs. Season and cook on each side until golden.
In a bowl, mash together the avocado, lime juice, and a pinch of salt.
To make the chimichurri sauce, add all ingredients to a small bowl and mix until combined.
Warm the tortillas in a pan until lightly browned on each side.
Add the avocado to the tortillas, followed by the steak, corn, diced tomatoes, and chimichurri sauce. Finish with a sprinkle of feta.
