Prep (15 minutes – The Foundation of Flavor):

1. 1. Preheat Oven (Getting Ready to Roast): Preheat your oven to 425°F (218°C). Preheating the oven ensures that the chicken and vegetables cook evenly and develop a nice char.
   2. Prepare Baking Sheet (The Easy Cleanup): Line a large sheet pan with parchment paper or foil for easy cleanup. Parchment paper prevents the food from sticking to the pan and makes cleanup a breeze. Foil is also a good option, but parchment paper is generally preferred for baking.
   3. Slice Chicken (The Protein Prep): Slice the chicken breasts into ¼-inch strips. This ensures even cooking and makes them perfect for fajitas. You can also buy pre-sliced chicken strips to save time.
   4. Slice Vegetables (The Veggie Power): Cut the bell peppers and onions into even strips, similar in size to the chicken. Uniformly sized pieces will cook at the same rate.
   5. Mix Seasoning (The Flavor Booster): In a small bowl, mix all the fajita seasoning ingredients together until well combined. This homemade seasoning blend is far superior to store-bought versions and allows you to control the level of spice.

Season and Arrange (5 minutes – The Flavor Infusion):

1. 1. Combine Ingredients (The Flavor Party): Place the sliced chicken and vegetables on the prepared sheet pan.
   2. Drizzle and Sprinkle (The Flavor Shower): Drizzle the chicken and vegetables with olive oil and lime juice. This helps the seasoning adhere and adds moisture. Then, sprinkle the fajita seasoning mixture evenly over everything, ensuring that all the chicken and vegetables are well coated.
   3. Toss and Spread (The Even Distribution): Toss everything together thoroughly to coat evenly, making sure that all the chicken and vegetables are well seasoned. Spread the mixture in a single layer on the sheet pan, ensuring nothing overlaps. Overlapping can cause the ingredients to steam instead of roast, leading to less flavorful and less crispy fajitas.

Cook (20-25 minutes – The Magic Happens):

1. 1. Bake (The Roasting Process): Bake the sheet pan chicken fajitas in the preheated oven at 425°F (218°C) for 20-25 minutes.
   2. Stir (The Even Cooking): Stir the mixture halfway through cooking to ensure even browning and prevent sticking. This also helps the vegetables to caramelize and the chicken to cook through evenly.
   3. Check for Doneness (The Temperature Check): Cook until the chicken reaches an internal temperature of 165°F (74°C). This is crucial for food safety. Use a meat thermometer to check the temperature – insert it into the thickest part of a chicken strip.
   4. Optional Broil (The Final Char): For extra char and a slightly smoky flavor, broil the fajitas for 2-3 minutes at the end of cooking. Keep a close eye on them to prevent burning!

Serve (The Grand Finale):

1. 1. Warm Tortillas (The Perfect Wrap): Warm the tortillas according to package directions. You can warm them in a skillet, microwave, or oven. Warming the tortillas makes them more pliable and prevents them from tearing when you fill them.
   2. Assemble (The Fun Part): Assemble the fajitas with the cooked chicken and vegetables. Let everyone customize their own fajitas with their favorite toppings.
   3. Add Toppings (The Flavor Explosion): Add your desired toppings, such as fresh cilantro, sour cream or Greek yogurt, guacamole or diced avocado, pico de gallo or salsa, shredded cheese, and lime wedges. Toppings add a burst of fresh flavor, creamy texture, and extra richness to the fajitas.
   4. Squeeze Lime (The Citrus Burst): Squeeze fresh lime juice over the assembled fajitas for a final burst of citrusy goodness. Lime juice brightens up the flavors and adds a refreshing tang.
   5. Serve Immediately (The Best Enjoyment): Serve the fajitas immediately while they’re hot and the tortillas are warm. This is when they taste their absolute best!
