Marinate the Steak: In a shallow dish, combine olive oil, garlic, soy sauce, smoked paprika, lemon juice, salt, and black pepper. Add the skirt steak and marinate for at least 15 minutes.
Preheat the Grill: Preheat your grill or grill pan over medium-high heat.
Grill the Steak: Place the marinated steak on the grill and cook for 3-4 minutes per side for medium-rare. Adjust the cooking time based on your preferred doneness.
Rest the Steak: Remove the steak from the grill and let it rest for 5 minutes before slicing against the grain.
Prepare the Lemon Herb Couscous Salad
Cook the Couscous: Bring the vegetable broth to a boil in a saucepan. Stir in the couscous, cover, and remove from heat. Let it sit for 5 minutes, then fluff with a fork.

Dress the Salad: Add lemon zest, lemon juice, olive oil, salt, and pepper. Toss to combine.
Assemble and Serve
