01 - Bring a large pot of salted water to a rolling boil. Add pasta and cook until al dente according to package directions. Drain thoroughly and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add sliced sausage in a single layer and cook for 3-4 minutes, turning occasionally, until evenly browned and caramelized.
03 - Add sliced onion to the skillet and sauté for 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 dissolve the tomato paste and honey, scraping up any browned bits from the bottom of the skillet. Bring to a gentle simmer.
05 - Return cooked pasta to the skillet. Toss vigorously to coat evenly in the sauce. Reduce heat to medium-low and simmer for 4-5 minutes, stirring frequently, until sauce thickens and clings to the pasta.
06 - Remove from heat. Season with chili flakes and black pepper to taste. Spr with fresh parsley and serve immediately while hot.
