01 - Preheat the oven to 350°F.
02 - Pat the pork belly dry with paper towels. Rub salt and black pepper into the skin and meat.
03 - Place pork belly skin-side up on a rack in a roasting tray. Roast for 1 hour, then increase oven temperature to 430°F and roast for a further 10-15 minutes until the skin is crispy and golden.
04 - Remove from oven and let rest for 10 minutes. Slice the pork belly into bite-sized pieces.
05 - In a small saucepan, combine rice vinegar, soy sauce, honey, ketchup, and brown sugar. Bring to a simmer over medium heat. Add cornstarch slurry and cook, stirring, until thickened and glossy. Remove from heat.
06 - Heat vegetable oil in a large non-stick skillet over medium-high heat. Add sliced pork belly and fry until edges are extra crispy, about 2-3 minutes.
07 - Drizzle the sweet and sour sauce over the crispy pork, tossing to coat evenly. Remove from heat.
08 - In a large bowl, toss salad greens, cucumber, carrot, cherry tomatoes, red onion, bell pepper, and cilantro.
09 - Divide the salad among serving plates. Top with the crispy sweet and sour pork belly.
10 - Sprinkle with peanuts, sesame seeds, and chili slices. Serve immediately.
