01 - Bring a large pot of salted water to boil. Cook pasta until al dente according to package directions. Drain thoroughly and set aside.
02 - Heat olive oil in a large skillet over medium-high heat. Add sliced sausage in a single layer and cook for 3-4 minutes until well-browned and caramelized on both sides.
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 pan. Bring to a gentle simmer.
05 - Add cooked pasta to the skillet and toss to coat evenly. Reduce heat to medium-low and simmer for 4-5 minutes, stirring occasionally, until sauce thickens and clings to the pasta.
06 - Remove from heat. Season with red pepper flakes and black pepper to taste. Sprinkle with fresh parsley and serve immediately while hot.
