01 - Cook pasta in a large pot of salted boiling water until al dente, then drain and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add sliced sausage and cook for 3-4 minutes until caramelized.
03 - Add onion to the skillet and sauté until softened, about 3 minutes. Stir in minced garlic and cook for 1 minute until fragrant.
04 - Pour in chicken broth, soy sauce, honey, and tomato paste. Stir to combine, scraping up browned bits from the skillet bottom. Bring to a gentle simmer.
05 - Return cooked pasta to the skillet. Toss to coat evenly in sauce and simmer for 4-5 minutes, stirring occasionally, until sauce thickens and clings to pasta.
06 - Season with chili flakes and black pepper to taste. Remove from heat, sprinkle with fresh parsley, and serve immediately.
