Marinate the Chicken: In a large bowl, whisk together sweet chili sauce, soy sauce, garlic, ginger, honey, and sesame oil. Add chicken breasts and toss to coat. Cover and refrigerate for at least 30 minutes or up to overnight.
Cook the Chicken: Heat a grill pan or skillet over medium-high heat. Cook chicken for 5–7 minutes per side, or until fully cooked and slightly caramelized. Let rest for 5 minutes, then slice.
Make the Mango Salsa: In a medium bowl, combine diced mango, red onion, jalapeño, red bell pepper, cilantro, garlic, olive oil, lime juice, salt, and pepper. Mix well and chill until ready to serve.
Make the Dressing: In a small bowl, whisk together sour cream (or yogurt), sweet chili sauce, rice vinegar, maple syrup, garlic powder, smoked paprika, salt, and pepper. Thin with a little water until desired consistency is reached.
Assemble the Bowls: Divide cooked rice among bowls. Top with sliced chicken, mango salsa, shredded cabbage, and avocado. Drizzle with creamy sweet chili dressing and add any optional toppings.
