Preheat the grill and make the rub: If using bamboo skewers, soak them in a bowl of water to prevent them from burning on the grill. Pre-heat the grill to medium-high heat, about 400°F. In a small jar with a lid, toss together the seafood rub ingredients.
Prepare the shrimp: Peel and devein shrimp if necessary. Then skewer shrimp on soaked bamboo skewers. Six shrimp per skewer is a good amount. Season shrimp liberally with seafood rub—you won’t use all of it.

Serve: Shrimp and couscous are best to serve right away. If you have leftovers, reheat shrimp in a skillet over low heat until warmed through. Do not microwave. Shrimp will keep in the fridge for a few days.

Cook the couscous: In a small pot set over medium-high heat, bring water and butter to a simmer. When butter is melted, stir in couscous and remove from heat and cover with a lid. Let steam for five minutes to cook couscous. Then stir in lemon pepper and fresh lemon zest.
