Start by whisking together your olive oil, lemon juice, honey, garlic, Dijon mustard, oregano, salt, and pepper in a bowl. Pour half of this mixture over the skirt steak, making sure it’s completely coated. Let the steak marinate for at least 30 minutes at room temperature or up to two hours in the fridge.
While the steak marinates, cook the Israeli couscous according to package instructions in salted boiling water. Once done, drain and rinse under cold water to stop cooking. Toss the warm couscous with the reserved marinade to soak up flavor and chill in the fridge.
Preheat your grill to medium-high heat and cook the skirt steak for about 3–4 minutes per side, depending on thickness. Once grilled, let the steak rest for 10 minutes before slicing it thinly against the grain — this keeps it tender, not chewy.
Take your chilled, dressed couscous and fold in the chopped cucumber, scallions, dill, parsley, and crumbled feta. Toss gently so everything is evenly coated and looks vibrant.
Plate up a generous bed of couscous salad and lay slices of juicy skirt steak on top. Add a final squeeze of lemon and a sprinkle of flaky sea salt for that extra burst of freshness.
