3-Step Execution Protocol

Preheat & Prep

Preheat grill to 450°F (232°C). Clean and oil grates. Prepare chicken fajitas (sliced chicken & peppers) (1.5 lbs boneless skinless chicken breasts marinated in lime juice, garlic, cumin, and chili powder, grilled whole over high direct heat then sliced into strips). Spray lightly with high-smoke-point oil.

Cook & Flip

Cook for 10–12 mins. Flip at the 6-minute mark for even browning.

Check & Rest

Dark grill marks, clear running juices, firm spring to touch, instant-read reads 165°F before slicing into strips. Confirm internal temperature reaches 165°F (74°C) internal. Rest for 5 minutes before serving.

Verification Basis & Testing Rig

USDA FSIS 165°F Poultry Safe Cooking Minimum; Weber Southwest Grilling Protocol.

Pro Tip: Always grill the marinated chicken breasts whole rather than pre-slicing into strips; whole breasts retain internal juices and do not slip between the grill grates.
