One of my favourite salads for the summer months.
Whisk together all of the dressing/marinade ingredients in a small bowl.
Place the steak in a glass or ceramic dish. Drizzle with HALF of the dressing. Cover and place in the fridge, turning occasionally, for 2 hours to develop the flavours.
Once marinating is complete, cook steak for 2-3 minutes each side (medium). Transfer to a plate. Cover and set aside for?10 minutes to rest.
Place the cucumber, tomato, red onion, mint, coriander, rocket and basil and crushed cashews in a large bowl. Thinly slice steak across the grain and add to the salad. Drizzle with remaining dressing and gently toss to combine. Divide salad between serving bowls and serve immediately.
To bulk this salad up, you can add some cooked quinoa and/or avocado.
