Step-by-Step Instructions for Chicken Fajita Lettuce Wraps
Preparing this fresh and vibrant meal is incredibly simple, making it the perfect choice for busy weeknights when you want something healthy yet satisfying. By searing the chicken at a high temperature, you will lock in all those delicious juices while creating a beautiful golden crust.

Step 1: Sear the Chicken
- Heat the olive oil in your large skillet over medium-high heat until it shimmers beautifully.
- Add the thin chicken strips carefully to the hot pan to avoid splattering.
- Sauté the chicken for 5 to 6 minutes, stirring occasionally, until it turns a gorgeous golden-brown. If the chicken starts to stick, simply add a tiny splash of water to deglaze the skillet.

- Toss the sliced red bell pepper, yellow bell pepper, and red onion directly into the skillet with the chicken.
- Sprinkle the savory fajita seasoning evenly over the entire mixture.
- Cook for an additional 5 minutes, stirring frequently, until the vegetables are tender-crisp and beautifully caramelized.
Step 3: Assemble the Wraps
- Spoon generous portions of the hot chicken fajita mixture into the center of each butter lettuce leaf.
- Top each wrap with rich, creamy avocado slices and a sprinkle of freshly chopped cilantro.
- Serve immediately while the filling is warm and the lettuce is delightfully cool.
