Reddit reviews Ortega Seasoning Mix, Reduced Sodium Fajita, 1.25 Ounce (Pack of 12)

Yep - you need a large skillet.

• Mission Fajita Grade Flour Tortillas (personally I avoid corn tortillas)
  
• Ortega or McCormick, or Taco Bell Fajita seasoning
  
• 1 lb Chicken breast
  
• 1 or 2 Bell Peppers
  
• 1 Onion (yellow preferred)
  
• Mexican, Cheddar Jack, or Taco Cheese
  
• Sour Cream (optional)
  
• ~2 Tbps Olive oil
  
  Cut the chicken up into about 1" cubes.
  Cut the pepper up into thin strips.
  Dice the onion.
  Fry the chicken up on high heat in the 2Tbps of olive oil until no longer pink. I like a browned crisp on some of the pieces. If too much water comes out of the chicken you may want to drain it and increase the heat.
  Add the diced onion, and pepper, add spice packet and HALF the water per directions. There's a lot of water in the onion and pepper so only use half what it says on the pack. Cook uncovered medium-high heat stirring for ~5 minutes.
  Lightly wet a tortilla and nuke it in the microwave for about 30 seconds to soften it if you like. Take it out and hop it between your hands until ~dry. It'll be a little hot. Sour cream, fajita stuffings, cheese on top, wrap it all up.
  
  *Whenever cooking with chicken you've gotta get the trash out of the house / apartment. Never leave uncooked chicken remnants or packaging in the trash for more than 12 hours or it will smell TERRIBLE!
