Combine all ingredients (add the shrimp at the end) for the marinade and let sit in a bowl or bag for 20-30 minutes. Skewer the shrimp and grill - about 2-3 minutes per side - on a hot grill. Remove and serve with the rice/quinoa.
For the Rice and Quinoa
On high heat, warm the stock up to almost a boil and add the basmati and quinoa as well as the pepper and garlic to the saucepan. Bring back to a boil, turn the heat down to the lowest setting and cover, cooking for 15 minutes. Season with some kosher salt and add the chopped cilantro. Stir in and serve with the grilled shrimp.
