Campfire Foil Packet Chicken Fajitas

1. Build a coal-friendly fire. Start your campfire and let it burn down until you have a steady bed of hot coals. You want consistent heat, not tall flames. Coals cook. Flames just stress you out.
2. Mix the seasoning. In a small bowl, combine chili powder, cumin, smoked paprika, salt, garlic powder, and black pepper.
3. Toss the filling. In a large bowl (or a zip-top bag), toss chicken, peppers, and onion with oil, the spice mix, and the juice from 1/2 lime until everything is evenly coated.
4. Assemble foil packets. Tear off 4 large sheets of heavy-duty foil (about 18 inches each). Divide the mixture among the centers, keeping each packet no more than about halfway full so the heat can circulate and everything cooks evenly. If using the water or salsa, add a small splash to each packet. Fold into sealed packets: bring long sides together, fold down tightly, then crimp the ends. Keep the seal tight so steam stays inside.
   
5. Cook over coals. Place packets on a grill grate over coals or set them on the edge of the coal bed (not directly in flames). Cook 7 to 8 minutes, then flip with tongs and cook 6 to 8 minutes more, until chicken reaches 165 F. Campfire heat varies, so use cues too: the packets should be puffed, steaming, and sizzling steadily. If your strips are closer to 1/2 inch thick, plan on a few extra minutes.
   
6. Rest, then open carefully. Transfer packets to a plate or tray and let them rest 2 minutes. Open away from your face because that steam is not playing around.
7. Warm tortillas. Warm tortillas briefly on the grate or in a dry skillet until flexible and lightly toasted.
8. Finish and serve. Squeeze remaining lime wedges over the fajita filling. Pile into tortillas and top with cheese, salsa, cilantro, and anything else you packed like a genius.
   

Matt tip: If you want a little more smoky char, crack the packet open for the last 1 to 2 minutes of cooking and let some steam escape. A tightly sealed packet is mostly a steam situation, so venting a bit helps browning. Watch closely so nothing dries out.
