In a mixing bowl, whisk together the olive oil, ground cumin, smoked paprika, garlic powder, salt, and pepper until well combined.
Rub this flavorful spice mixture all over the flank steak, ensuring it is evenly coated. Cover and allow it to marinate for a minimum of 30 minutes, or up to 2 hours in the refrigerator for a depth of flavor.
Preheat your grill or a grill pan over medium-high heat. Remove the marinated steak from the bowl, shaking off any excess marinade. Grill the steak for approximately 4-5 minutes on each side, achieving medium-rare, or adjust the cooking time to your preferred level of doneness.
Once cooked, transfer the steak to a cutting board and let it rest for at least 5 minutes. This allows the juices to redistribute, ensuring every slice is tender and juicy. After resting, slice the steak against the grain into thin strips.
While the steak is resting, prepare the quinoa salad mix. In a large bowl, combine the cooked quinoa with halved cherry tomatoes, diced cucumber, thinly sliced red onion, and halved kalamata olives. Drizzle the mixture with fresh lemon juice and toss gently until everything is evenly distributed.
To assemble each bowl, start with a generous base of the quinoa salad mixture. Arrange the sliced steak artfully on top and finish with a sprinkle of crumbled feta cheese and a handful of chopped parsley for freshness.
Notes
Serve in deep, rustic bowls and garnish with extra olive oil and lemon wedges.
