In a jug or bowl, whisk all the ingredients for the marinade. (1 tablespoon toasted sesame oil, 2 tablespoons sriracha sauce, 2 garlic cloves, 1/4 cup honey, 1/4 cup soy sauce, 2 tablespoons rice vinegar, 1/4 cup tomato paste, ¼ cup harissa paste, and Kosher salt and pepper)
Pour half of the mixture over the 1 pound chicken breast pieces and stir to evenly coat.
Allow the chicken to marinate for 30 minutes at the counter, or overnight in the fridge. Reserve the remaining sauce to use for the stir fry.
Heat a large pan over medium heat. Drizzle with 1 tablespoon olive oil and add the marinated chicken in a single layer. Cook undisturbed for 4-5 minutes, then stir and continue to cook until the chicken is almost cooked through.
Stir in the 1 medium sweet onion and 1 large red or orange bell pepper. Continue to cook, stirring often, for around 5 minutes, or until the chicken is fully cooked through. Pour over the reserved sauce and stir to combine; remove from heat.
Serve over cooked rice and garnish with toasted sesame seeds and wedges of lime, if desired.
Notes
Marinate overnight: For deeper flavor, let the chicken marinate overnight in the fridge.
Don’t skip the sesame seeds: They add a nice crunch that makes this dish pop.
Serve with rice: This Firecracker Chicken is perfect over cooked rice to soak up that delicious sauce.
