Cut the chicken into 3x2 rectangles and season with sazon completo. Cut 1/2 an onion and 1/2 green pepper into quarters. Add everything into the pressure cooker and cover with water.
Cook in the pressure cooker on high heat/high pressure for 10 minutes.
Release the pressure and remove the chicken from the water. Using two forks shred the chicken into long strips. Cut 1 and ½ onions into slices.
Cover a large sauté pan with oil and place on high heat. Once hot, add the chicken and the onions. Cook for about five minutes. Stir in the lime juice, and sazon completo and stir. Cook for another10-15 minutes until the chicken starts to become brown and crispy. Add salt to taste.
Serve over a bed of rice and enjoy!
