1 pound shelled and deveined large shrimp (26 to 30 per lb.)
1 cup couscous
4 firm-ripe tomatoes, halved
Chopped fresh mint leaves
How to Make It
Heat grill to high (450° to 550°). In a small bowl, combine harissa, 2 tbsp. each oil and lemon juice, 2 tsp. zest, the cumin, and 1/2 tsp. salt. Put shrimp in a medium bowl, toss with half the sauce (reserve the rest), and let stand 10 minutes. Thread shrimp onto metal skewers.
Prepare couscous as package directs, adding remaining 1 tsp. zest. Fluff with a fork and gently stir in 1 tbsp. oil and remaining 1 tbsp. lemon juice and 1/2 tsp. salt. Set aside.
Brush tomatoes with remaining 1 tbsp. oil. Grill shrimp and tomatoes, covered, turning once, until shrimp is opaque and tomatoes are softened, about 4 minutes. Serve with couscous plus a sprinkle of mint, more salt to taste, and remaining sauce.
