How to Make It
Cook the couscous according to the package directions.
Combine the clementines, vinegar, 3 tablespoons of the oil, and ¼ teaspoon each salt and pepper in a medium bowl. Add the endive, almonds, and chives and toss to combine.
Heat the remaining tablespoon of oil in a large nonstick skillet over medium-high heat. Season the fish with ½ teaspoon salt and ¼ teaspoon pepper. Cook until opaque throughout, 3 to 4 minutes per side.
Serve the couscous topped with the citrus salad and fish, drizzled with any remaining dressing.
