  • cup vegetable oil
  • 2 teaspoons chili powder
  • 1 teaspoon dried oregano
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon ground cumin
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 pinch ground cayenne pepper
  • 2 pounds chicken tenders or thighs
  • 4 cups sliced bell peppers any color
  • 1 onion sliced
  • ¼ cup chopped fresh cilantro
  • ½ lime juiced
  • 16 fajita flour tortillas


  • Combine, chili powder, oregano, garlic, onion, cumin, salt, pepper, and cayenne pepper (if I'm in a hurry, I'll just use ½ packet of taco mix seasoning and add a couple of shakes of chili powder, instead of pulling out the individual spices) in a large resealable plastic bag or big bowl. Add chicken tenders, oil, bell peppers, and onion; shake to mix.
  • Marinate chicken mixture in the refrigerator, 30 minutes to 2 hours.
  • Preheat oven to 400° F (200° C). Line a rimmed sheet pan with aluminum foil. Spread chicken mixture onto prepared pan.
  • Roast in the preheated oven, stirring halfway through, until chicken is no longer pink and bell peppers soften, 15 to 20 minutes.
  • Sprinkle cilantro and pour lime juice over chicken mixture; toss to distribute. Serve in warmed tortillas (two flour tortillas is a fast carb portion, or 3 corn tortillas).
  • Save the leftovers for lunches later in the week!
  • Note: You can also do this stove top if you prefer! Slice chicken and veggies (keep separate). Cover chicken with spices and set aside. Heat oil in a skillet over medium-high heat, and add sliced vegetables. Saute until slightly browned 2-4 minutes, push veggies to one side of the pan (or remove) and add chicken. Saute for an additional 4-5 minutes, add veggies back in and saute together until chicken is no longer pick, and veggies are tender. Then follow step 5 above.
