Ingredients

  • 2 chicken breasts, sliced into strips
  • 1 bell pepper, sliced
  • 1 onion, sliced
  • 2 tablespoons fajita seasoning
  • 2 cups shredded cheddar cheese
  • 8 flour tortillas
  • 1 tablespoon vegetable or olive oil

Instructions

  • Prep ingredients: Slice chicken breasts, bell pepper, and onion into thin strips
  • Heat 1 tablespoon of oil in a skillet over medium-high heat, then cook chicken strips for 5–7 minutes until golden
  • Add sliced bell peppers and onions to the skillet, stirring in fajita seasoning. Cook for 5 more minutes until vegetables retain slight crunch
  • Place 1 tortilla in a clean skillet, layer ½ cup cheese, half the chicken mixture, and another ½ cup cheese
  • Cover with a second tortilla, then cook for 2–3 minutes per side until golden and melty
  • Repeat with remaining tortillas and fillings, then slice each into wedges and serve warm

Notes

Use a non-stick skillet for easier flipping
Add a dash of chili powder to the mix for extra heat
Letting the quesadILLA rest prevents cheese from melting
Store leftovers in an airtight container for up to 3 days
