01 - Heat olive oil in a large, deep skillet or Dutch oven over medium heat.
02 - Add sliced chicken sausage and sauté for 3–4 minutes until lightly browned. Remove and set aside.
03 - Add onion and red bell pepper to the same pan. Sauté for 2–3 minutes until softened.
04 - Stir in garlic and zucchini; cook for another 2 minutes until fragrant.
05 - Add orzo and toast, stirring constantly, for 1 minute to enhance nutty flavor.
06 - Pour in chicken broth and add grape tomatoes, oregano, basil, smoked paprika, and red pepper flakes. Season with salt and black pepper.
07 - Bring to a boil, then reduce heat to a simmer. Cover and cook for 8–10 minutes, stirring occasionally, until orzo is tender and most liquid is absorbed.
08 - Return browned sausage to the pot and add spinach. Stir until spinach wilts and everything is heated through, about 2–3 minutes.
09 - Remove from heat. Taste and adjust seasoning with salt and pepper if needed.
10 - Serve hot, garnished with grated Parmesan and fresh herbs if desired.
