### Instructions
1. **Prepare the chicken:** Pat the chicken pieces dry with paper towels. Season lightly with salt and pepper.
2. **Cook the chicken:** Heat the olive oil or sesame oil in a large skillet or wok over medium-high heat. Add the chicken pieces in a single layer and cook for 3-5 minutes per side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
3. **Sauté aromatics:** In the same skillet, add the minced garlic and grated ginger. Sauté for 30 seconds until fragrant, being careful not to burn the garlic.
4. **Make the sauce:** Whisk together the sweet chili sauce, soy sauce, rice vinegar, sesame oil (for the sauce), and chicken broth (or water) in a small bowl. Pour the sauce into the skillet with the garlic and ginger. Bring to a gentle simmer.
5. **Thicken the sauce:** Slowly whisk in the cornstarch slurry. Continue to stir until the sauce thickens to your desired consistency (it should coat the back of a spoon).
6. **Combine and serve:** Add the cooked chicken back into the skillet with the thickened sauce. Toss gently to coat all the chicken pieces evenly.
7. **Garnish and enjoy:** Serve hot over steamed rice, noodles, or with a side of your favorite stir-fried vegetables. Garnish with chopped green onions and sesame seeds if desired.
### Short Tips
* **Marinate for extra flavor:** For an even deeper flavor, marinate the chicken in a tablespoon of soy sauce and a teaspoon of sesame oil for at least 30 minutes before cooking.
* **Adjust the spice:** If you like more heat, add a pinch of red pepper flakes to the sauce. If you prefer it milder, you can reduce the amount of sweet chili sauce slightly.
* **Don’t overcrowd the pan:** Cook the chicken in batches if necessary to ensure it browns properly and cooks evenly. Overcrowding can steam the chicken instead of searing it.
* **Make it saucier:** If you prefer a lot of sauce, you can increase the quantities of the sauce ingredients slightly.
* **Meal prep friendly:** This dish reheats well, making it a great option for meal prepping throughout the week.
