Instructions
- Prep the Oven:

- Cook the Cajun Shrimp:
- In a large skillet heat olive oil over medium-high for about two minutes Toss shrimp with one tablespoon Cajun seasoning Coat every piece evenly to ensure bold flavor Sauté shrimp for two to three minutes just until pink and curled Remove shrimp from skillet do not overcook or they will be tough
