01 - Cook pasta in a large pot of salted boiling water until al dente. Drain thoroughly and set aside, reserving a small amount of pasta water if needed.
02 - Heat olive oil in a large skillet over medium heat. Add sliced sausage and cook for 3-4 minutes, turning occasionally, until well caramelized on both sides.
03 - Add sliced onion to the skillet and sauté for approximately 3 minutes until softened and translucent. Stir in minced garlic and cook for 1 minute until fragrant, being careful not to burn.
04 - Pour in chicken broth, soy sauce, honey, and tomato paste. Stir thoroughly to combine, scraping up any browned bits from the bottom of the skillet. Bring the mixture to a gentle simmer.
05 - Return the cooked pasta to the skillet. Toss vigorously to coat evenly in the sauce. Let simmer for 4-5 minutes, stirring occasionally, until the sauce thickens and clings nicely to the pasta.
06 - Season with chili flakes and black pepper to taste. Remove from heat immediately and sprinkle generously with fresh parsley. Serve hot while the sauce is still glossy and sticky.
