Grilled Prawns and Vegetables with Pearl Couscous

This vibrant grilled prawns and vegetables with pearl couscous dish is a sophisticated take on a Mediterranean salad, making it a perfect choice for those seeking a high-protein meal that doesn't compromise on flavour. Large, juicy prawns are lightly charred alongside wedges of red onion and sliced courgette, all tied together by a zesty herb and red wine vinegar dressing. The addition of saffron-infused pearl couscous provides a wonderful, nutty texture that soaks up the savoury juices beautifully.

Ideal for a light summer dinner or an impressive weekend lunch, this recipe is as nutritious as it is colourful. The combination of fresh oregano and thyme brings a fragrant depth to the seafood, while the crumbled feta adds a creamy, salty finish. Serve it warm straight from the grill or at room temperature for a relaxed, alfresco dining experience that feels both healthy and indulgent.

How to make Grilled Prawns and Vegetables with Pearl Couscous

Whisk together vinegar, oregano, thyme, garlic, 1/2 teaspoons salt, and 1/4 teaspoons pepper in a small bowl until salt is dissolved. Add 80ml oil in a slow stream, whisking until vinaigrette is combined.

Heat 1 tablespoon oil in a wide 3-quart heavy saucepan over moderate heat until hot but not smoking, then toast couscous, stirring occasionally, until fragrant and pale golden, 3 to 5 minutes. While couscous toasts, stir together broth, water, and saffron in a large glass measure. Add to couscous with 1/2 teaspoons salt and bring to a simmer, uncovered. Simmer, covered, until liquid is absorbed and couscous is al dente, 10 to 12 minutes. Remove from heat and let stand, covered, 10 minutes. Stir vinaigrette to combine, then stir 2 tablespoons into couscous and let stand, uncovered, at room temperature.

Prepare grill for cooking over medium-hot charcoal (moderate heat for gas).

Toss prawns with 1 tablespoon oil, 1/4 teaspoons salt, and 1/4 teaspoons pepper in a bowl and thread 4 or 5 prawns onto each skewer (don't crowd, or prawns won't cook evenly).

Peel onions and trim root ends slightly, leaving ends intact, then halve lengthwise and cut halves lengthwise into 1/2-inch-wide wedges. Insert 1 wooden pick through each wedge to hold layers together while grilling, then put onions in a large bowl with courgette. Toss vegetables with remaining 2 tablespoons oil, 1/2 teaspoons salt, and 1/4 teaspoons pepper.

Grill prawns skewers on lightly oiled grill rack, covered only if using a gas grill, turning over once with tongs, until just cooked through, about 4 minutes total. Transfer prawns, discarding skewers, to a clean bowl and toss with 2 tablespoons vinaigrette.

Grill vegetables on lightly oiled grill rack, covered only if using a gas grill, turning over once, until just tender, about 5 minutes, transferring to bowl as grilled. Remove and discard picks from onions. Drizzle vegetables with remaining vinaigrette and toss to combine.

Spoon couscous onto a large platter or shallow serving bowl. Arrange prawns and vegetables on top of couscous and sprinkle with feta. Serve warm or at room temperature.
