Marinate the Chicken: In a bowl, combine sweet chili sauce, soy sauce, rice vinegar, sesame oil, garlic, chili flakes, salt, and pepper. Add chicken and marinate for 20–30 minutes.
Cook the Chicken: Heat a nonstick pan over medium heat. Add the marinated chicken and cook for 5–6 minutes per side until golden and fully cooked. Let rest, then slice.
Make the Sauce: In a small bowl, whisk together sweet chili sauce, mayonnaise or Greek yogurt, and lime juice until smooth.
Assemble the Bowls: Add a layer of cooked rice to each bowl. Top with cucumber slices and sliced chicken.
Drizzle and Garnish: Spoon the chili-lime sauce over the chicken. Finish with sesame seeds and sliced green onions.
Serve: Enjoy warm for a balanced and refreshing meal.
