Start by marinating the chicken breasts. In a bowl, combine the sweet chili sauce, soy sauce, grated ginger, minced garlic, salt, and pepper. Add the chicken and coat well. Let it marinate for at least 30 minutes, or up to 2 hours in the refrigerator for more flavor.
Preheat a large skillet or wok over medium-high heat. Add the sesame oil and olive oil.
Once the oil is hot, add the marinated chicken breasts to the skillet. Sear each side for about 5-7 minutes or until golden brown and fully cooked through (internal temperature should reach 165°F or 75°C).
Remove the chicken from the skillet and set aside on a plate. Using the same skillet, add the sliced red bell pepper and broccoli florets. Stir-fry for about 3-4 minutes until the vegetables are bright and tender-crisp.
Return the chicken to the skillet with the vegetables, and pour any remaining marinade over the top. Allow everything to heat through for another 2-3 minutes, stirring gently to combine.
Once heated, remove from heat and plate the chicken and vegetable mixture.
Sprinkle sliced green onions and sesame seeds over the top for garnish before serving.
Notes
Serve over a bed of steamed jasmine rice or quinoa, and add lime wedges for a zesty kick.
