In a mixing bowl, add the shrimp, one tablespoon of olive oil, and 2 tablespoons of the taco seasoning and mix well. Add the lime juice and mix that through.
Heat the remaining olive oil in a non-stick skillet. Once hot, add the onion and peppers, along with the remaining tablespoon of taco seasoning, and cook for 4-5 minutes, until the vegetables have softened.
Remove the vegetables from the skillet and add the shrimp. Cook the shrimp for 3-4 minutes, or until no longer pink.
Add the vegetables back into the skillet and mix everything together until combined.
Serve with tortillas and your favorite fajita toppings.
