Sheet Pan Beef Fajitas

Sheet Pan Beef Fajitas

Background and History:

Fajitas are a Tex-Mex culinary treasure, with their roots tracing back to Mexican ranch cuisine. Originally, they were made with throwaway cuts of beef like skirt steak, which was marinated and grilled. This modern adaptation simplifies the preparation by roasting all the ingredients together on a sheet pan, creating a flavorful and fuss-free dish.
