01 - Whisk together olive oil, lemon juice, garlic, smoked paprika, cumin, salt, and pepper in a bowl. Coat the skirt steak thoroughly with the marinade. Let sit at room temperature for 20 minutes to absorb flavors.
02 - Bring water or broth to a boil in a medium saucepan. Stir in pearl couscous, reduce heat to low, cover, and simmer for 10 minutes until tender. Drain any excess liquid and allow to cool slightly.
03 - Preheat a grill or grill pan over high heat. Grill the marinated skirt steak for 3-4 minutes per side for medium-rare doneness, adjusting time for preferred doneness. Transfer steak to a plate, tent loosely with foil, and rest for 5-10 minutes before slicing.
04 - Combine cooked couscous, cherry tomatoes, cucumber, red onion, parsley, and mint in a large bowl. Whisk olive oil, lemon juice, lemon zest, salt, and pepper in a separate small bowl. Pour dressing over salad and toss thoroughly to coat evenly.
05 - Slice the rested skirt steak thinly against the grain. Arrange steak slices over a generous bed of pearl couscous salad and serve immediately.
