In a medium bowl, combine the shrimp, oil, and spices. Use right away or cover with plastic wrap and marinate in the fridge for up to 24 hours.
Heat a large heavy-duty non-stick pan to medium-high heat for 2 minutes. Once the pan is hot, coat the pan with a light drizzle of oil (if using a non-stick pan) and cook the shrimp in batches for 2 minutes per side or until charred and cooked through. Do not over-crowd the pan. Serve on tacos, salads, burritos, or rice. Enjoy!
