Chef Emma’s Helpful Tips
- Make-Ahead Advice: You can marinate the steak and vegetables in the fajita seasoning a few hours ahead or even overnight for deeper flavor.
- Slicing Tricks: For the most tender steak, slice against the grain. This not only helps with tenderness but also makes for beautiful presentation.
- Storage Suggestions: Any leftover fajitas can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or on the grill.
- Perfect Tortillas: Warm your tortillas on the grill for a few seconds before serving. This elevates the texture and adds a lovely char!
