My DIL turned me onto this site and told me to check out the sheet pan recipe for chicken fajitas. She thought it would be right up my alley as I LOVE to roast just about everything. We have fajitas or tacos quite often ... using chicken, shrimp, halibut or beef. I have tried this w/ beef, but it's so hard to find skirt steaks in my market, I make steak fajitas a different way. But if you can get skirt steak or cut your steak in small enough slices, this would work well .... just don't overcook you beef.
I find it's way easier to slice the chicken breast when it is still a bit frozen. You can always just buy presliced chicken fajita meat at your store --- if you're lucky to find a store that offers that option. My local meat dept is a hit or miss w/ presliced fajitas meat and I typically have chicken breast in my freezer.
As I've mentioned in the past, I do brine my chicken for about 4 hours, but you DO NOT need to do that step, it's just what I do to keep chicken moist and tender.
Serve w/ your favorite toppings: guacamole, salsa, sour cream and enjoy!

Place chicken, bell peppers, onion and garlic in a single layer onto the prepared baking sheet. Stir in olive oil and chili powder mixture; gently toss to combine. (I put chicken and veggies in a large bowl, sprinkle w/ spice mix, add oil, toss THEN place on sheet pan).
