Step 1

Pour 1/3 cup of the brown sugar mixture over chicken; cook and stir until the brown sugar mixture has a syrup-like consistency, 6 to 7 minutes.

Step 4
Pour in the remaining brown sugar mixture; cook until chicken is tender and no longer pink inside, about 5 minutes.

Step 5
Stir in in peanuts, jalapenos and green onion; cook until warmed through, 2 to 3 minutes.

Step 6
Garnish with cilantro and serve.
