For the fajitas:

  • 8 oz boneless skinless chicken breast, cut into strips
  • 1 red bell pepper sliced
  • 1 yellow bell pepper sliced
  • 1 red onion thinly sliced
  • ½ tbsp oregano
  • 1 tsp cumin

Instructions
 

  • Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
  • Prepare the fajitas: In a large bowl, toss the chicken strips, bell peppers, and onion with olive oil, oregano, cumin, chili powder, garlic, salt, and pepper until well coated.
  • Roast: Spread everything in a single layer on the prepared baking sheet and bake for 20-25 minutes, flipping halfway, until the chicken is cooked through and the vegetables are tender.
  • Make the guacamole: While the chicken is roasting, mash the avocado in a small bowl and mix in the lemon juice, if using.
  • Assemble: Once the fajitas are ready, spoon the mixture onto romaine lettuce leaves, top with chopped tomatoes and guacamole, and enjoy!
