Method:
Place salmon, zucchini, bell pepper and onion in a shallow baking dish and sprinkle with salt and pepper. Whisk together garlic, rosemary, olive oil and lime juice in a small bowl. Pour mixture over salmon and vegetables, toss and marinate 15 to 30 minutes.
Preheat the grill or broiler. Skewer the salmon and vegetables, reserving marinade, and grill or broil 5 to 7 minutes, turning once, until salmon is cooked through and vegetables are tender. While cooking, boil the marinade in a small saucepan for 5 minutes. Drizzle over skewers and serve.
