Instructions

1. Make the Marinade

   Time: PT5M

2. Slice the Chicken

   Trim any fat from the chicken breasts and slice into bite‑size strips about 1/2 inch wide.

   Time: PT5M

3. Marinate the Chicken

   Place the chicken strips in a Ziploc bag, pour the marinade over them, seal the bag removing excess air, and massage the chicken so every piece is coated.

   Time: PT3M

4. Let the Chicken Marinate

   Refrigerate the bag for at least 10 minutes, ideally 2 hours. You can also marinate overnight, but no longer than 8 hours to avoid overly soft texture.

5. Pre‑heat the Skillet

   Heat a cast‑iron skillet over medium‑high heat and add 1 tbsp vegetable oil, swirling to coat the surface.

   Time: PT2M

   Temperature: medium‑high heat

6. Cook the Chicken

   Add the marinated chicken strips in a single layer. Cook 4‑5 minutes per side, or until the interior reaches 165°F (74°C) and the edges are lightly charred.

   Time: PT10M

   Temperature: medium‑high heat

7. Set Chicken Aside

   Transfer the cooked chicken to a plate and keep warm.

   Time: PT1M

8. Sauté Vegetables

   Add a splash more oil to the same skillet, then add sliced onion, bell peppers, and optional jalapeño. Stir‑fry 5‑7 minutes until they reach your desired tenderness.

   Time: PT6M

   Temperature: medium heat

9. Combine Chicken and Veggies

   Return the chicken to the skillet, toss with the vegetables, and heat through for another 2 minutes.

   Time: PT2M

   Temperature: medium‑high heat
