📜 History & Background
Fajitas originated in Texas and northern Mexico, traditionally made with grilled skirt steak. The word “fajita” comes from “faja,” meaning “strip” in Spanish, referring to the way the meat is cut.
Originally a humble dish prepared by ranch workers, fajitas grew into a globally loved meal, especially in Tex-Mex cuisine. The slow cooker version is a modern adaptation, making it easier to prepare while preserving its bold, smoky flavors.
🧪 Formation (How It Works)
- Slow cooking breaks down tough fibers in steak → tender texture

- Covered cooking traps moisture → juicy, not dry
