01 - Heat the olive oil in a large, deep skillet or Dutch oven over medium heat.
02 - Add the sliced chicken sausage and sauté for 3–4 minutes until lightly browned. Remove and set aside.
03 - In the same pan, add the onion and red bell pepper. Sauté for 2–3 minutes until softened.
04 - Stir in the garlic and zucchini; cook for another 2 minutes.
05 - Add the orzo and toast, stirring, for 1 minute.
06 - Pour in the chicken broth and add the 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 the orzo is tender and most of the liquid is absorbed.
08 - Return the browned chicken sausage to the pot and add the spinach. Stir until the spinach wilts and everything is heated through, about 2–3 minutes.
09 - Remove from heat. Taste and adjust seasoning if needed. Serve hot, garnished with Parmesan and fresh herbs if desired.
