Preheat oven to 425°F.
In a large bowl, combine shrimp with harissa, yogurt, garlic, lime juice spices, parsley, and olive oil. Cover and allow to marinate for 15 minutes.
Place 4 shrimps on each skewer and place on baking tray.
Put in the oven and roast just until pink and firm - about 8 to 9 minutes.
Serve immediately!
