You can serve the shrimp fajitas with tortillas, but it is important to warm them accurately. You can use a few methods, and we recommend that you warm them before serving. A simple method of warming them is to take a damp paper towel and wrap a stack of five tortillas in it.  Then, you must microwave the stack for at least thirty seconds or until it is warm. Ensure that you keep them in aluminum foil after they are warm so they don't dry out. You can also just heat the tortillas on the stove on medium-low heat.
