Creating a delicious Sweet Chili Chicken is straightforward, and these steps will guide you to culinary success:

1. Prepare the Ingredients: Gather all ingredients and cut the chicken into bite-sized pieces.
2. Marinate the Chicken: In a bowl, combine sweet chili sauce, soy sauce, salt, and pepper. Add the chicken pieces and let them marinate for at least 10 minutes.
3. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat.
4. Cook the Chicken: Add the marinated chicken to the skillet and cook until golden brown and cooked through, about 5-7 minutes.
5. Add Aromatics: Stir in the minced garlic and ginger, cooking for an additional 1-2 minutes until fragrant.
6. Add Peppers: Toss in the sliced bell peppers, cooking for another 3-4 minutes until they are tender but still crisp.
7. Combine and Glaze: Pour any remaining marinade over the chicken and vegetables, mixing thoroughly to coat everything in the sauce.
8. Finish Cooking: Allow everything to cook together for another minute or two, ensuring even coating and flavor absorption.
9. Garnish: Remove from heat and sprinkle with green onions and sesame seeds for an elegant touch.
10. Serve Immediately: Transfer your Sweet Chili Chicken to a serving dish and enjoy!
