Heat the oil in a large frying pan and cook the vegetables for a couple of minutes until they begin to soften.
Add the fajita seasoning and prawns to the pan. Stir well to ensure that everything is coated evenly in the seasoning and cook for a few more minutes until the prawns have turned pink and are cooked through.
While the prawns are cooking, heat the fajitas according to packet instructions.
When cooked, squeeze over the lime juice and serve with the warmed tortillas. Add the cheese, sour cream, salsa, guacamole and jalepenos.
