Ingredients

• For the Homemade Chicken Fajita Seasoning:
• 1 tbsp chili powder
• 1 tbsp ground cumin
• 1 tsp smoked paprika
• 1 tsp garlic powder
• 1 tsp onion powder
• ½ tsp dried oregano
• 1 tsp salt (plus more to taste)
• ½ tsp black pepper
• ¼ tsp cayenne pepper (optional, for heat)
• Pinch of sugar (optional, balances flavors)
• For the Fajita Filling:
• 1 ½ lbs boneless, skinless chicken breasts, sliced into thin strips
• 2 tbsp olive oil (or other high-heat oil)
• 1 large red bell pepper, sliced into thin strips
• 1 large green bell pepper, sliced into thin strips
• 1 large yellow onion, sliced into thin strips
• Juice of 1 lime (about 2 tbsp)
• ¼ cup water or chicken broth (optional, for deglazing)
• For the Sandwich Build:
• 4 sturdy sandwich rolls (hoagie rolls, bolillo, or French rolls recommended)
• 8 slices Provolone or Monterey Jack cheese
• Optional toppings: quick pickled red onion, fresh cilantro, sliced avocado
• For a Quick Creamy Fajita Spread:
• ½ cup mayonnaise (or Greek yogurt for a lighter option)
• 1 tsp of the homemade fajita seasoning mix
• 1 tsp lime juice

Directions

1. Mix the Seasoning: In a small bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, dried oregano, salt, black pepper, optional cayenne, and pinch of sugar. Stir well until fully combined. This is your secret weapon!
2. Prep & Season the Chicken: Slice your chicken breasts evenly into thin strips, about ¼-inch thick. This ensures fast, even cooking. In a medium bowl, toss the sliced chicken with 1 tablespoon of the seasoning mix. Hold off on adding extra salt to the chicken at this stage, as the seasoning already contains some.
3. Sear the Chicken: Heat 1 tablespoon of olive oil in a large skillet (cast iron works beautifully for that perfect sear) over medium-high heat until shimmering. Add the seasoned chicken in a single layer, ensuring not to overcrowd the pan. Cook for 3-4 minutes per side, until golden brown and cooked through. Remove the chicken from the skillet and set aside. (An instant-read thermometer should register 165°F/74°C for doneness).
4. Cook Peppers & Onions: Add the remaining 1 tablespoon of olive oil to the same skillet (no need to clean it – those browned bits add flavor!). Add the sliced bell peppers and onions. Sprinkle with another ½ to 1 teaspoon of your homemade fajita seasoning mix. Cook over medium-high heat for 7-10 minutes, stirring occasionally, until the vegetables are tender-crisp and have developed some nice browning, not just steaming. If the pan gets too dry, add a splash of water or broth to deglaze, scraping up any flavorful bits.
5. Combine & Finish the Filling: Return the cooked chicken to the skillet with the peppers and onions. Add the lime juice and stir everything together. Cook for another 1-2 minutes, allowing any excess liquid to reduce slightly. Taste and adjust seasoning if needed. You want a flavorful, slightly saucy but not watery filling.
6. Make the Fajita Spread: While the filling finishes, in a small bowl, whisk together the mayonnaise (or Greek yogurt), 1 teaspoon of the homemade fajita seasoning, and 1 teaspoon of lime juice until smooth.
7. Assemble & Toast the Sandwiches:
   1. Slice your sandwich rolls lengthwise, but not all the way through, creating a pocket.
   2. Spread a generous amount of the creamy fajita spread on both cut sides of each roll. This not only adds flavor but acts as a barrier against sogginess.
   3. Divide the chicken fajita filling among the rolls.
   4. Top the filling with 2 slices of Provolone or Monterey Jack cheese.
   5. You can toast the assembled sandwiches in the same skillet (wiped clean) over medium heat, covered, for 2-3 minutes until the cheese is melted and the bread is lightly toasted. Alternatively, place them under a broiler for 1-2 minutes (watch carefully!).
   6. Add any optional toppings like pickled red onion, cilantro, or avocado before serving.
