# Expert Advice:

01 -
  • The spice blend hits every note—smoky, earthy, with just enough warmth to make things interesting
  • One pan means twenty minutes of hands-off time while your oven does the heavy lifting
  • Leftovers pack perfectly for tomorrow's lunch, if they make it that far
02 -
  • Cutting meat against the grain makes all the difference between chewy and tender—look for the muscle fibers running in one direction and slice perpendicular to them
  • Don't skip the high heat or you'll miss out on that caramelized sweetness that makes fajitas sing
03 -
  • The baking sheet cleanup is infinitely easier if you line it with parchment or foil first
  • If you have time, let the meat marinate in the spices and oil for up to 2 hours—the difference is noticeable
